✨ [FFL-2857] Feature Flags tab — team filtering + token revocation (stacked PR 4 of 4)

[kellyw1806]

Motivation

Stacked on #4912 (flag overrides). Adds team/creator filtering + per-flag descriptions to the Feature Flags tab, plus production OAuth support and token revocation on disconnect.

Stack (review bottom-up)

	PR	Base	What it adds	Status
1 of 4	#4913 · FFL-2597	main	OAuth sign-in	✅ merged
2 of 4	#4916 · FFL-2858	ffl-2597	catalog browsing	✅ merged
3 of 4	#4912 · FFL-2596	main	flag overrides	in review
4 of 4	this · FFL-2857	ffl-2596	team filter + token revocation	draft

⚠️ Base is kelly.wang/ffl-2596 (#4912) — merge that first. Kept as a draft until #4912 lands; this then retargets to main and gets a quick rebase.

Changes

• Team & creator filters (server-side): "My feature flags" → created_by=<uuid>; "My teams" → tags=team:<handle>. Identity (user UUID + team handles) comes from /api/v2/current_user + /api/v2/team?filter[me]=true. "My teams" is a checkbox dropdown showing an "N selected" summary.
• Per-flag description in each row (catalog description attribute), with a "Show more" expander that only appears when the text is actually clamped.
• Production OAuth: per-site client id (getClientId — staging vs prod); site picker trimmed to US1 + Staging.
• Token revocation on disconnect (RFC 7009 /oauth2/v1/revoke — revokes the refresh token, clears local tokens either way).
• Scope-retry: falls back to the required scopes if the OAuth client isn't granted the optional teams_read (via invalid_scope redirect or an authorize page-load failure).

DEMO

Note, we can now choose between datadoghq.com and staging. There are also filters for My Feature Flags and My Teams. Descriptions are fetched as well.
