a11y: AUTO / VOD / REC streamer chips keyboard-accessible

The three streamer-row action chips (AUTO toggle, VOD toggle, REC
one-shot) were spans wired only with click listeners. Same a11y
gap as the .remove X chips in 4.6.50: no role, no tabindex, no
keyboard activation, no semantic state for toggles. Screen readers
read them as raw text "AUTO", "VOD", "REC" with no clue they were
interactive controls.

Factored a wireChipButton helper inside renderStreamers and ran all
three chips through it. The helper stamps:
- role="button" + tabindex="0"
- aria-label (locale-driven, picked up the existing
  autoRecordTitle / autoVodTitle / recordLiveTitle locale keys
  that were previously only used for the visual title-tooltip)
- aria-pressed="true"/"false" for the AUTO and VOD toggles so
  AT announces the on/off state
- A keydown handler that synthesises the same click handler on
  Enter / Space and stops propagation so the row's click handler
  (streamer-select) does not also fire

CSS adds three focus-visible rings (green for AUTO, blue for VOD,
red for REC) matching each chips active-state colour palette.
Keyboard navigators tabbing through a streamer item now see the
ring on the focused chip clearly.
