feat(ui): friends list as lobby-style rows with kebab + confirm modals

Settings -> Friends previously rendered each friend as a bordered card with
two always-visible text buttons (Remove / Block) that fired immediately. Rework
the whole screen to the lobby's visual language: one-line rows split by
hairline separators across all three sections (friends, incoming requests,
blocked).

Each friend row gains a right-hand kebab that slides the row open to reveal two
icon actions split by a vertical divider -- block (no-entry) and remove (cross)
-- mirroring the lobby's slide-to-reveal. Both actions now require a
confirmation modal; since the slide moves a short name off-screen, the modal
keeps a generic title and shows the friend's name in the body, above the
buttons, so a long name cannot stretch the sheet. Incoming keeps its
accept/decline buttons and blocked keeps unblock, inline on their rows.

Add the friends.actions / friends.blockConfirm / friends.unfriendConfirm keys
to both i18n catalogs and document the flow in FUNCTIONAL (+_ru).
