feat(profiles): let each profile hide clubs it doesn't carry

[rickyt19]

Adds per-profile club visibility (issue #283). Profile.settings gets an enabled_clubs list; the club picker filters against it, defaulting to showing everything for existing profiles.

What does this PR do?

Adds a per-profile club-visibility toggle. Each profile can now hide clubs
it doesn't carry from the club picker; other profiles are unaffected, and
existing profiles with no customization still see every club (unchanged
behavior). Fixes #283.

Why was this required?

We share one kiosk between people with different bags. Everyone had to
scroll past clubs they don't own every time they picked a club. Hiding
unused clubs per-profile makes club selection faster, especially on the
touchscreen.

Automated tests

• tests/test_profiles.py: new TestSetEnabledClubs class covering
  ProfileStore.set_enabled_clubs — valid ids accepted, invalid ids dropped,
  dedup, unknown profile_id rejected, non-list rejected, empty list and
  full-club-set both treated as "unfiltered", and persistence round-trip.
• tests/test_server.py: handle_set_profile_clubs broadcasts enabled_clubs
  correctly, and is a no-op on an unknown profile id.
• ui/src/components/panel/pickerSections.test.ts: filterSectionsByEnabledClubs
  — unchanged on undefined/empty, filters per-section, drops emptied
  sections, ignores unknown ids.
• ui/src/components/panel/ClubVisibilityDialog.test.tsx: title, club
  listing/grouping, pre-check behavior, Save/Cancel presence.
• ProfilesPanel.test.tsx: aria-label for the new manage-clubs button per
  profile.

Manual (human) testing

Ran on a Raspberry Pi kiosk (start-kiosk.sh --sim --camera-capture, real
camera hardware) and in a desktop browser against the same server.

• Opened a profile's club-visibility dialog, unchecked several irons/woods,
  saved, and confirmed the in-game club picker only showed the remaining
  enabled clubs for that profile.
• Switched to a different profile and confirmed it still showed its own
  (unfiltered) full club list, unaffected by the other profile's setting.
• Confirmed picker tile size stays constant regardless of how many clubs
  are enabled (previously it visibly resized as the filtered count changed).
• Verified the manage-clubs icon renders correctly on both the Pi's
  Chromium-fallback kiosk browser and a desktop browser (the original emoji
  icon rendered as a missing-glyph box on the Pi, which has no emoji font).
• Confirmed the club-visibility grid no longer requires scrolling on the
  Pi's kiosk screen at 800px width.
