feat(ui): UI revamp — Phase 1 foundation + Phase 2 power-browsing + Phase 3 bulk actions (#571)

## Summary

Complete implementation of the three-phase UI revamp from
`docs/superpowers/specs/2026-04-20-ui-revamp-design.md` — Phase 1
foundation, Phase 2 power-browsing, and Phase 3 bulk actions — in a
single branch of 104 atomic commits on top of `main`. Everything the
design doc scoped is shipped, minus the two items the plan itself
flagged as deferred (relationship graph view, saved views).

Despite the misleading `feat/ui-revamp-phase-1a` branch name (the branch
was created when scope was still Phase 1 only, and the name stuck), the
actual delivery covers all three phases.

Every commit builds, vets, and tests independently — split by concern so
bisect stays useful. Individual `fix(ui):` commits ship with Playwright
regression guards where the fix is observable (scroll, flex shrinkage,
alignment, flash). Full branch green on `golangci-lint`, `go test ./...`
(skipping `TestLDAPIntegration` which needs a live AD), and `go test
-tags e2e ./internal/e2e` (202-user seed, 71 s full run).

## Phase 1 — Foundation

Stack migration and new visual system.

- **Pico CSS v2 + htmx + Alpine.js (CSP build)**, vendored.
Tailwind/TypeScript/PostCSS/bun toolchain dropped.
- **New `app.css`** with AAA-verified hybrid theme tokens (see
`TestAppCSSTokensMeetAAAContrast`). Dark: monospace IDE palette; Light:
sans neutral.
- **Command palette** (`⌘K` / `/`) with live search across all loaded
users, groups, computers — served from an ETag-cached
`/api/search-index.json`.
- **Side-panel detail drawer** for users/groups/computers. Three-pane
layout at wide viewports (OU rail · list · drawer), disclosure-collapsed
at narrow.
- **Pivot links** inside every drawer (open full page, member-of,
manages, OU peers, etc.).
- **Recents** (client-side, localStorage) and **pinned** (server-side
bbolt store, per-user).
- **Dark/light theme + compact/comfortable density** toggles;
preferences initialised via external JS (CSP-compliant).
- **Full-page detail views** on F5 of any `/users/:dn`, `/groups/:dn`,
`/computers/:dn?fragment=drawer` URL.
- **AAA conformance** on every new surface. `@media
(prefers-reduced-motion)` respected across transitions.
- **Reimplementation of all existing routes** in the new system (home,
list, detail, login, logout, error pages).

## Phase 2 — Power browsing

From `2026-04-20-ui-revamp-phase-2-3-consolidated.md`, everything except
saved views (flagged low-priority).

- **Faceted filters** on every list page: OU, enabled/disabled,
last-logon window (24 h / 7 d / 30 d / never), member-of. Chips wire up
to query-string params.
- **OU tree rail** — distinct immediate-OU values populated from the
cache, toggleable secondary filter on `/users`, `/groups`, `/computers`.
- **Inline attribute edit** in the drawer for users (email, description,
displayName, title, department, company, telephone, mobile, office).
- Saved views / named searches: deferred.

## Phase 3 — Advanced

Bulk multi-select + batch actions shipped; graph view explicitly
deferred in
`docs/superpowers/specs/2026-04-20-ui-revamp-phase-3-graph-view-deferred.md`
("AAA for node-graph visualisations is its own research").

- **`/users/bulk`**: `add-to-group`, `remove-from-group`, `delete`,
`disable` (AD-gated — OpenLDAP returns 501 because `userAccountControl`
is not portable).
- **`/groups/bulk`**: `add-members`, `delete` (via `simple-ldap-go`
v1.12's generic `DeleteByDN`).
- **`/computers/bulk`**: `delete` (same generic) and `disable`
(AD-gated).
- **Session-backed flash** via `setFlash` / `takeFlash` — every bulk
path queues a `templates.Flash` before the redirect; the receiving list
handler pops it and renders "Deleted N / M groups." / "Disabled N …" /
partial-failure / total-failure banners above the filter row. Flash
consumed on read.
- Relationship graph view: deferred.

## Beyond the design doc

Work that fell out of implementation and isn't in any of the three phase
specs:

- **Nested group management** — parent ↔ child edges on `/groups/:dn`
with cycle detection via BFS over `collectAncestorDNs` /
`collectDescendantDNs`, depth cap 32.
- **`AdminCount`-based Privileged badge** — replaces the English CN
allowlist. Reads `User.AdminCount` (new in `simple-ldap-go` v1.12)
mapped from AD's `adminCount=1`. Catches localised AD directories, no
caller-side walks.
- **Humanised LDAP-error flash** — modify handlers now pipe AD errors
(Code 50 / 20 / 32) through `humaniseLDAPError` into a drawer-level
`drawer__flash--error` banner. "Insufficient Access Rights" no longer
looks like a silent success.
- **Header stability under long lists** — `flex-shrink: 0` on topnav and
topnav-secondary so body-flex pressure from 8k-row lists can't collapse
their padding. Regression guard at
`TestHeaderDoesNotShrinkWithLongLists`.
- **Scroll invariants** — `html:has(> body.has-page-scroll) { height:
auto; overflow: visible }` releases the list-page shell's clip when body
opts into page scroll. F5 on fragment URLs produces a scrollbar again.
Guarded at `TestFragmentURL_DirectNavIsScrollable`.
- **Alignment fixes** — reset Pico's default `label { margin-bottom }`
on inline chip labels; select-all chip now baselines with the search
input.
- **`simple-ldap-go` upgraded to v1.12.0** — new `DisableUser` /
`EnableUser` / `DisableComputer` / `EnableComputer` methods, new
`User.AdminCount` field, exported `ACCOUNTDISABLE` constant. [Release
notes.](https://github.com/netresearch/simple-ldap-go/releases/tag/v1.12.0)

## Test plan

- [ ] `make check` — lint + vet + unit tests (currently: 0 lint issues,
all unit tests pass)
- [ ] `go test -tags e2e ./internal/e2e/` — Playwright harness against
OpenLDAP testcontainer, 202-user bulk seed. Target: green (last local
run: 71 s)
- [ ] Exercise against a live AD:
- [ ] Bulk-delete a throwaway group from `/groups`, confirm "Deleted N
group(s)." flash
- [ ] Disable a test user from the drawer on an AD account, confirm
flash + bit 0x2 set in `userAccountControl` via another tool
- [ ] Confirm the Privileged shield renders next to users with
`adminCount=1`
- [ ] F5 on `/users/:dn?fragment=drawer` — scrollbar + full shell
present
- [ ] Resize `/users` viewport to 700 px with >100 rows — topnav /
topnav-secondary stay at natural height
- [ ] Dark mode + compact density — AAA contrast holds on every banner /
badge
- [ ] Verify `simple-ldap-go` v1.12.0 resolves (`go mod why
github.com/netresearch/simple-ldap-go`)

## Explicitly not in this PR (deferred by the design docs)

- **Relationship graph view** — needs its own AAA research before
implementation. See
`docs/superpowers/specs/2026-04-20-ui-revamp-phase-3-graph-view-deferred.md`.
- **Saved searches / named views** — low priority once the command
palette landed.

## Notes

- Disable is AD-only, gated in both the handler
(`a.ldapConfig.IsActiveDirectory`) and the template (button renders only
when `vm.IsAD`). Non-AD deployments keep the 501 `bulkNotImplemented`
contract.
- `AdminCount` is sticky in AD — `true` means "is or was privileged",
not a real-time check. Good for badging, not for authorisation
decisions. Documented inline in upstream `User.AdminCount` and in
`adminUserDNs`.
- No backwards-compatibility shims — the old `_v1` templates and
handlers are gone in favour of `_v2`. Out-of-tree code referencing them
needs a follow-up.
- Branch name (`feat/ui-revamp-phase-1a`) predates the scope expansion;
renaming a branch mid-PR is disruptive, so leaving it.
