Simplify Deployments tabs and fix duplicate Version button

Deployments page:
- Remove redundant context chips (US East, Development, 24h) — topbar already shows these
- Rename Timeline tab → Pipeline with appropriate icon
- Remove Table tab (raw data table, low value vs Pipeline view)
- Remove Correlations tab (deployment correlations belong in Pipeline view)
- Keep only Pipeline + Approvals tabs

Releases Versions tab:
- Fix duplicate "New Version" button — ReleaseListComponent now accepts
  [embedded]="true" to suppress its pageAction when rendered inside the
  unified Releases page (which already has "New Release" page action)
