fix: 6 UX regressions — popups, themes, cursor, selection, status bar

Popup windows (tools/editor/help):
- CSP script-src 'self' blocked Tauri's inline IPC bridge scripts in
  child WebviewWindows. Added 'unsafe-inline' to script-src. Still
  restrictive (was null before SEC-4).

Theme application:
- Watcher on sessionStore.activeTheme needed { deep: true } — Pinia
  reactive proxy identity doesn't change on object replacement
- LocalTerminalView.vue had ZERO theme support — added full applyTheme()
  with watcher and mount-time application
- Container background now syncs with theme (was stuck on CSS variable)

Cursor blink:
- terminal.focus() after mount in useTerminal.ts — terminal opened
  without focus, xterm.js rendered static outline instead of blinking block

Selection highlighting:
- applyTheme() was overwriting theme without selectionBackground/
  selectionForeground/selectionInactiveBackground — selection invisible
  after any theme change
- Removed !important from terminal.css that overrode canvas selection
- Bumped default selection opacity 0.3 → 0.4

Status bar:
- h-6 text-[10px] → h-8 text-xs (24px/10px → 32px/12px)
