build(website): enable the strictest tsconfig flags that already pass (#15300)

*PR Created by the Glary-Bot Agent*

---

## Summary

`astro/tsconfigs/strictest` layers nine options on top of the `strict`
preset the app already uses. Measured each against `apps/website`: seven
report zero errors once six dead declarations are removed. This turns
those seven on.

## Changes

- **What**: enables `noUnusedLocals`, `noUnusedParameters`,
`noImplicitReturns`, `noFallthroughCasesInSwitch`, `noImplicitOverride`,
`allowUnreachableCode: false`, `allowUnusedLabels: false`, and deletes
the six declarations that blocked them:
  - `data/drops.ts` — `FEATURED_BADGE` (unused `LocalizedText`)
  - `layouts/BaseLayout.astro` — unused `Locale` type import
- `pages/careers.astro` + `pages/zh-CN/careers.astro` — `siteUrl`
destructured but never read
  - `scripts/generate-models.ts` — unused `RawModel` interface
- `components/product/enterprise/TeamSection.vue` — `routes` computed
and its `getRoutes` import
- **Breaking**: none. Every deletion is a declaration with no reader.

## Review Focus

**Measured, not guessed.** Error counts per flag against this app:

| flag | errors | enabled here |
|---|---:|:---:|
| `noUnusedParameters` | 0 | yes |
| `noImplicitReturns` | 0 | yes |
| `noFallthroughCasesInSwitch` | 0 | yes |
| `noImplicitOverride` | 0 | yes |
| `allowUnreachableCode: false` | 0 | yes |
| `allowUnusedLabels: false` | 0 | yes |
| `noUnusedLocals` | 6 | yes (fixed here) |
| `exactOptionalPropertyTypes` | **75** | no |
| `noUncheckedIndexedAccess` | **202** | no |

The last two are left off deliberately — each needs its own remediation
pass, not a flag flip. `noUncheckedIndexedAccess` in particular would
touch every array index and `Record` lookup in the app.

`TeamSection.vue` is only reachable by `vue-tsc`, which this app does
not run yet (that arrives in #15284). It is fixed here anyway so the
flag stays clean once that lands.

## Verification

`astro check` 0 errors with the flags on · 422 unit tests passing (1
pre-existing `minimaxMusic3` failure, also on `main`) · production build
595 pages · oxfmt clean.

Confirmed the new flags introduce no `vue-tsc` regressions: `vue-tsc`
reports the same 9 pre-existing SFC errors as `main` (same four files,
same counts — those are what #15282/#15283 fix), and **zero**
TS6133/TS6196/TS7027/TS7030 diagnostics, i.e. none attributable to these
flags. This PR is therefore independent of that stack and can merge in
any order relative to it.
