Declutter the channel-manager tags row:
- New reusable ActionMenu (⋯) on the AnchoredPopover platform — a compact
overflow menu of one-shot actions with optional pending/disabled + spinner.
The two big glass buttons (Read subscriptions, Backfill everything) move into
it, freeing the row.
- The "YOUR TAGS" caption becomes a "✎ TAGS" trigger button that opens the tag
editor directly, retiring the separate "Manage tags" button.
Adds i18n (channels.actionsLabel, channels.tags.label; HU+EN). ActionMenu is
built to be reused for other overflow menus later. Self-E2E'd: ⋯ opens the two
actions, ✎ TAGS opens the manager. gate green (tsc/eslint-0/prettier).
