Deep-review follow-up on R13 S3.
- Add a roving-keyboard-nav test proving a disabled ActionMenu item is
skipped by arrow keys, and assert the stats "left" row renders the
formatEta value (formatEta had no coverage anywhere).
- Remove the disabledIndices plumbing from AnchoredPopover + ActionMenu:
it was redundant. useListNavigation already skips items via their DOM
disabled/aria-disabled attribute, and PopoverItem renders a native
disabled button — verified against @floating-ui/react 0.27
isListIndexDisabled and by a mutation test. Behaviour is unchanged and
now guarded by the new test.
- ActionMenu: skip disabled items in roving keyboard nav (plumb
disabledIndices through the AnchoredPopover platform); a pending
action no longer strands focus on an unfocusable button.
- ActionMenu + ChannelStatsPopover: add type="button" to the popover
triggers so they can't submit an enclosing form.
- ChannelStatsPopover: restore the per-stat explanations as a native
title on each row — the guidance the old inline stats showed is back.
- i18n: drop the now-dead channels.tags.yourTags / .manage keys (en+hu);
the stats *Hint keys are live again via the restored row titles.
- test: cover ActionMenu (open/select/close/disabled) and
ChannelStatsPopover (rows, conditional ETA row, per-row hint title).
