feat: 5 dramatic extra themes (neon/terminal/blueprint/sunset) + board/review/layout polish

- Themes: add neon (cyber gradient), terminal (green CRT), blueprint (graph
  paper) and sunset (vaporwave) alongside the default Light (Y2K paper) and
  Dark. Theme toggle now cycles all; profile selector lists them; server
  validates against a shared whitelist.
- Bounty cards now show the project (customer) name.
- Remove the celebratory emoji from the empty Review Queue.
- Full-width h1 underline rule; My Tasks columns stack vertically for more
  room per task; card action buttons wrap/right-align so they never overflow.
