test(web): update TrackMenu spec for Android-parity kebab

The kebab gained "Start radio" and dropped the duplicate "Flag this track…"
(its action now lives solely under "Hide", which opens the same FlagPopover).
Net item count is unchanged (9 admin / 8 non-admin), but the named-item and
flag-entry assertions needed updating:
- mock playRadio in the store mock; assert Start radio dispatches playRadio.
- swap the flag-item presence check for start-radio.
- replace the "click Flag" test with "click Hide opens the popover".
