Fix own profile not updating after save + expand roadmap

- ProfileView: own profile now reads from user store directly instead of
  useProfile() hook, which only re-fetches on pubkey change — so the bio/
  name/avatar updates immediately after saving without needing to navigate away

- ROADMAP: added items from playtest feedback:
  - About/funding page (Bitcoin QR, Lightning, zap dev npub, Ko-fi/GitHub)
  - Mute/ignore user + anti-spam settings + WOT brainstorm note
  - Quote/repost (NIP-18)
  - Sidebar auto-hide + clearer collapse affordance
  - Profile helpers for newcomers (NIP-05, image upload)
  - Search improvements (NIP-50 relay detection, people search fallback)
  - UI/look & feel deferred until after Windows playtest
  - Long-form reading experience as a brainstorm session
