feat: Phase 3b — proper Web UI for memories, projects, settings

Replaces the debug /me + /connect pages with a real authed app shell.

Pages
- /                       — anonymous landing; redirects to /dashboard once signed in
- /dashboard              — recent memories + top projects, quick "new memory" action
- /memories               — searchable list with hybrid (vector+FTS+tags) scoring;
                            per-result rank breakdown shown inline
- /memories/[id]          — view + inline edit toggle + delete
- /memories/new           — create form with project autocomplete
- /projects               — list with memory counts and last-activity
- /projects/[key]         — that project's memories
- /settings               — read-only Authentik profile + link to tokens
- /settings/tokens        — list / create / revoke CLI tokens

Old URLs preserved as redirects:
- /me      → /dashboard
- /connect → /settings/tokens

Stack additions
- Tailwind v4 with CSS-first @theme tokens (dark only for now)
- App shell in app/(authed)/ — auth guard + top nav with global search box
- Lightweight UI primitives in app/_components/ui/ (Button, Input, Card,
  Badge, EmptyState, Container, PageHeader)
- Search logic extracted from MCP tool into lib/memories.ts so Web UI and
  MCP both call the same RRF code path
- Memory CRUD via Server Actions in lib/memory-actions.ts; audit_log
  rows are tagged actor='web' to distinguish from MCP writes

Per-token revoke
- New cli_tokens table (id, user_id, jti unique, name, created_at,
  last_used_at, expires_at, revoked_at) — migration 0001_cli_tokens.sql
- mintCliToken now records jti + name; verifyCliToken enforces revocation
  for tracked tokens. Legacy tokens minted before this change (no jti)
  are accepted on signature alone until they expire naturally.
- /settings/tokens lists active + revoked tokens with one-click revoke
