fix(security): Phase 0 critical hardening (guildModuleAccess enforcement)

[LucasSantana-Dev]

Summary

• 0.1 — Enforce requireGuildModuleAccess on guild routes (roles.ts, moderation.ts)
  • Roles routes (reaction-roles, roles/exclusive) now require overview:view access
  • Moderation routes (all 8 routes) now require moderation:view or moderation:manage access
  • Updated integration tests to mock guildAccessService for successful auth flows

Changes

• packages/backend/src/routes/roles.ts — Added requireGuildModuleAccess('overview', 'view') to both routes
• packages/backend/src/routes/moderation.ts — Added requireGuildModuleAccess('moderation', 'view'/'manage') to all 8 routes
• Updated test mocks to reflect guildAccessService checks

Risk

None. Both fixes are non-breaking:

• Roles routes are GET-only and no direct state changes
• Moderation routes now match the same pattern as management, automation, and moderation tabs already using the middleware
• All existing tests pass (750 passed)

Verification

• Type checking: ✓ Pass
• Linting: ✓ Pass (no new errors)
• Tests: ✓ 750 passed, 2 skipped

🚦 How do rate limits work?
