OAuth Client — Unified ApplicationRegistration, OAuth server, and frontend (#18267)

## Summary

Consolidates three separate PRs (#18260, #18261, #18262) into a single
unified branch with all review feedback addressed:

### New features
- **ApplicationRegistration entity** — server-level registration for
OAuth apps with encrypted server variables
- **OAuth 2.0 server** — authorization code, client credentials, refresh
token grants with PKCE support
- **OAuth discovery endpoint** —
`.well-known/oauth-authorization-server` metadata
- **Frontend UI** — app registration details page with credential
management, redirect URI editing, and server variable configuration
- **CLI integration** — `twenty dev` auto-registers apps and stores
OAuth credentials locally
- **Authorize consent screen** — OAuth consent page at `/authorize`
showing requested scopes

### Review feedback addressed

**Renames (PR #18260):**
- `appRegistration` → `applicationRegistration` (entity, tables, files,
imports, GraphQL types)
- `appRegistrationVariable` → `applicationRegistrationVariable`
- `clientId` → `oAuthClientId`, `clientSecretHash` →
`oAuthClientSecretHash`, `redirectUris` → `oAuthRedirectUris`, `scopes`
→ `oAuthScopes`

**Security fixes (PR #18261):**
- Fixed redirect URI validation bypass when `oAuthRedirectUris` is an
empty array
- Fixed workspace isolation in `clientCredentialsGrant` — now uses
`find()` with explicit handling for multiple installations
- Added error logging in refresh token `catch` block instead of silently
swallowing

**Code quality (PR #18262):**
- Split `VersionDistributionEntry` into its own file (one export per
file)
- Split GraphQL queries and mutations into individual files with a
shared fragment
- Removed unused `OAuth` entry from `AuthProviderEnum`
- Added loading state to `handleRotateSecret`
- Removed 27 narration-style comments from test files
- Added proper guards (`PublicEndpointGuard`, `NoPermissionGuard`) to
controllers and resolvers

## Test plan

- [ ] Verify `twenty dev` registers an app and stores OAuth credentials
- [ ] Test OAuth authorization code flow end-to-end (authorize → token →
API call)
- [ ] Test client credentials grant
- [ ] Verify redirect URI validation rejects requests when no URIs are
registered
- [ ] Verify app registration detail page renders correctly
- [ ] Test secret rotation with loading state
- [ ] Verify server variable editing and saving
- [ ] Run `npx nx database:reset twenty-server` to validate migration

Closes #18260, #18261, #18262
