sync: merge upstream whoabuddy/worker-logs (#16)

* feat: allow admin key to delete apps

Previously DELETE /apps/:id required the app's own API key. Now admins
can also delete apps using the X-Admin-Key header, consistent with
other admin operations.

* refactor: code simplifier pass 1 - remove dead code and consolidate utilities (#4)

* refactor: remove dead code and extract shared utilities

- Delete unused src/services/stats.ts (legacy KV-based stats, replaced by DO SQLite)
- Extract getAppDO and countByLevel to src/utils.ts
- countByLevel now uses Map for O(n) instead of O(n²) array scanning

* feat(dashboard): make branding configurable via env vars (#7)

Add BrandConfig type and getBrandConfig() that reads BRAND_* environment
variables with automatic accent color derivation and CDN URL composition.
Replace static CSS with buildBrandCss(config) generated from BrandConfig.
Thread brand config through router middleware and all page functions.

Includes comprehensive tests for brand config defaults, env overrides,
hex color validation, and accent fallback behavior.

Cherry-picked from #10 with conflict resolution
to preserve upstream wrangler.jsonc (no fork-specific environments).

* fix(auth): allow admin key for health-urls endpoint

The health-urls endpoint only accepted per-app API keys, preventing
admin users from configuring health check URLs. Switch to
requireApiKeyOrAdmin middleware to match the pattern used by other
app management endpoints.

Ported from #11.
