feat(121+122): smsplanet conversation, notifications, default footer

Phase 121 — SMSPLANET Conversation + Notifications:
- migration 20260512_000110 adds smsplanet conversation + notifications tables
- src/Modules/Sms (SmsConversationService, SmsMessageRepository, SmsplanetWebhookController)
- src/Modules/Notifications (Repository, Controller, ApiController)
- order SMS tab, notification center, sender mode, inbound webhook
- public notifications.js + layouts/app.php integration

Phase 122 — SMSPLANET Default SMS Footer:
- migration 20260512_000111 adds smsplanet_integration_settings.default_footer
- footer appended to test SMS and order SMS, validated against 918 char limit
- settings textarea + compact order SMS note when footer configured

Bundled (could not split per-phase without hunk staging):
- routes/web.php (also carries Phase 118 fakturownia redirects)
- DOCS/{ARCHITECTURE,DB_SCHEMA,TECH_CHANGELOG}.md (118 + 121 + 122 entries)
- .paul/codebase/{architecture,db_schema,tech_changelog}.md (118 + 121 + 122)
- .paul/STATE.md, ROADMAP.md, changelog/2026-05-12.md (UNIFY closure)

 - HostedSMS inbound replies: requires DCS/HostedSMS activation before implementation.
 - Phase 117 follow-up: run migration when XAMPP MySQL is online and manually test real SMSPLANET sends for Bearer token and key + password.
 - Phase 119 follow-up: `composer install` + `vendor/bin/phpunit tests/Unit/OrderImportRepositoryTest.php` to run the 3 new tests; manual smoke test re-syncing order #976 from shoppro to confirm `total_paid=91.00` persists across re-import.
+- Phase 121 follow-up: manually verify SMSPLANET settings/test send, inbound webhook insertion, order SMS tab, and notification polling/browser notification.
+- Phase 121 transition note: git commit was not created during UNIFY because the worktree contains unrelated Phase 118/local dirty files; prepare a scoped commit manually.
+- Phase 122 follow-up: manually verify settings save/reload and real SMSPLANET test/order sends with non-empty and empty footer; manually trigger over-limit final body rejection in UI.
+- Phase 122 transition note: git commit + ROADMAP/PROJECT evolution not executed during UNIFY because worktree contains uncommitted Phase 118 (Fakturownia single-instance) files. Resolve Phase 118 first or stage Phase 122 files in isolation.
