v0.11.9

Fixed

• The admin and agent panels were desktop-only. At a phone width every
  panel screen was 460-1093px wide: the 256px admin sidebar never folded
  away, the agent top nav ran off the screen with Back to App wrapped over
  three lines, and the Tickets table overflowed even a 1024px window. Below
  1024px the admin sidebar is now a drawer behind a menu button, and the
  agent nav folds into a menu. Every panel table scrolls sideways inside its
  card, with a shadow on the edge that has more, instead of widening the
  page; report, ticket and audit-log toolbars wrap.
• The agent Dashboard link was highlighted on every agent page, since
  every agent URL starts with its href. It now matches only the dashboard.
• Audit log entries were near-invisible on a light panel. They used fixed
  dark-mode colours; they now take the panel tokens.

Added

• Panel theme hooks for the pieces a host most often brands:
  activeText (current nav item), headerBg and headerText (admin top bar
  and agent top nav) and logoTileBg/logoTileFg (the square behind the
  logo). Each is optional and falls back to the token it replaces. Panel
  theming, including the existing tokens, is now documented in
  docs/theming.md.
