fix: make all CI jobs pass (integration, ui) and restore prefix dialog reset

Three failing test suites blocked CI. All three were test defects, not
application bugs.

Integration tests (integration/database.test.ts)
------------------------------------------------
The suite set NODE_ENV=test, which makes cache.cached() short-circuit both
its Redis read (src/lib/cache.ts:226) and its write (:249). A suite whose
stated purpose is exercising the real Redis path therefore never touched
Redis. Switched to NODE_ENV=development, the only non-production value
src/env.ts accepts, so the shared-cache code paths are genuinely covered.

Three assertions then needed correcting for real Redis semantics:

- `await cache.cached(...)` followed by `.resolves` can never hold: await
  yields a value, not a Promise. Assert the value directly.
- A cached negative result is stored as the JSON encoding of null, so
  `redis.get(key)` returns "null", not null.
- The news negative-cache key does not exist at all, so `ttl()` returned -2.
  Now that the write path is live the key is created and the TTL assertion
  holds as originally written.

UI tests (src/app/admin/prefixes/prefix-dialog.tsx)
---------------------------------------------------
The form-reset effect had `isOpen` removed from its dependency array. The
component returns null when closed, so the effect only ever ran on mount:
reopening the dialog no longer cleared the fields and a dismissed-but-
unsaved edit reappeared. Two tests in e2e/ui/unsaved-changes.spec.ts caught
this. Restored the dependency and documented why it is load-bearing.

The remaining edits in this branch drop stale biome-ignore comments that
suppressed useExhaustiveDependencies and noArrayIndexKey diagnostics. Where
the suppression had been load-bearing for behaviour, the underlying
dependency is now listed explicitly rather than silenced.

Verified: check (toolchain, audit, lint, i18n, typecheck), unit 3315
passed, integration 20 passed, UI 72 passed / 2 skipped.
