feat(banner): admin-controlled site banner above the header

hodyhq · hodyhq · commit 1cf903a276e4 · 2026-06-26T12:30:49.000-04:00
Adds a tenant-scoped notice that appears above the page header for
maintenance windows, releases, or incident announcements. Off by
default for existing installs; admin opt-in via Site Settings →
Banner.

Schema
- tenants.site_banner_enabled BOOL NOT NULL DEFAULT FALSE
- tenants.site_banner_message TEXT NOT NULL DEFAULT ''
- tenants.site_banner_variant VARCHAR(20) NOT NULL DEFAULT 'info'
- Migration is additive — no behavior change on upgrade.

Backend
- New action UpdateTenantSiteBanner validates variant against an
  allowlist (info|success|warning|danger|brand) and rejects an
  enabled banner with empty message. Max 500 chars.
- New cmd + postgres handler updates the three columns in one UPDATE.
- New POST /_api/admin/settings/site-banner endpoint.
- Tenant entity carries the three fields; rendered via existing
  Tenant context in views/base.html immediately inside &lt;body&gt;.

Frontend
- /admin/banner page with toggle / variant dropdown / 500-char
  message textarea / live preview / per-keystroke counter.
- _site-banner.scss owns the five variant palettes (info teal,
  success green, warning amber, danger red, brand var --color-primary).
  Responsive: tightens padding/font under 640px.
- No customer-facing render changes when disabled — the
  conditional in views/base.html elides the &lt;div&gt; entirely.
