## What & why
The audit-log viewer lived as a full-screen page reachable only via a
"View Logs" button buried in the **Security** tab. This surfaces it as
the **third tab in General settings** (`General | Security | Logs`),
consistent with the other tabs.
## Changes
- **Relocated** the event-logs module
`pages/settings/security/event-logs/` → `modules/settings/event-logs/`
and render it as tab content instead of a `FullScreenContainer` page.
Dropped `SettingsPath.EventLogs`, its route, and the fullscreen handling
in favor of the `general#logs` hash tab.
- **Security tab:** removed the "View Logs" entry; kept the
log-retention setting there.
- **In-tab gating** (shown to users with the Security permission):
Enterprise upgrade card when not entitled, a clear "ClickHouse not
configured" placeholder otherwise (derived from client config), and the
query is skipped when disabled. Replaces a bespoke error component that
string-matched error messages with the shared `SettingsEmptyPlaceholder`
/ `SettingsEnterpriseFeatureGateCard`.
- **Layout:** boxed content column with the table selector + filters
grouped in a `Card` and the results table below, matching settings
conventions. Kept the existing fixed filters (page/event name, member,
period) rather than recreating the record-view filter chips (those are
tightly coupled to record/view context).
Frontend + `twenty-shared` only — no changes to the log query or data.
## Test plan
- [x] `npx nx typecheck twenty-front` and `npx nx lint twenty-front`
pass
- [x] Settings → General shows three tabs; Logs is the third; breadcrumb
stays "Workspace / General"
- [x] With Enterprise + ClickHouse: table selector, filters, refresh,
and the paginated table work
- [x] Non-Enterprise: Enterprise upgrade card shown; no failing query
fires
- [ ] Enterprise without ClickHouse: shows the "ClickHouse not
configured" placeholder
- [ ] Security tab still shows the log-retention setting and the "View
Logs" button is gone
- [ ] A user without the Security permission sees neither the Security
nor Logs tab
