Redesign Support as bento hub, restore full sidebar, Western names

- Support Center overview rebuilt as a bento grid: large live-chat hero
  tile, support team tile, mini channel tiles and a recent-tickets strip.
- Restore full workspace sidebar (Workspace/Team/Profile groups) with a
  premium golden active state; unbuilt modules show a Coming Soon view.
- Use Western names across the UI (James Carter; Emma Wilson, Liam Foster,
  Sophie Turner, Noah Mitchell) incl. tickets, threads, portal demo user.
- Remove the Allottee card from Profile; add a clean Account & identity
  card and live-editable contacts.
- Relabel "Plot" -> "House number" everywhere; drop the allotment chip in
  favour of the property category.
- Premium visual pass: brand gradients, depth, glow accents, pill tabs.
