chore(web): remove frontend code and styles nothing reaches

The frontend JS is outside ESLint and knip, so this pass used an AST scan
(every method, function and top-level constant in src/web/public, counted
against identifiers, strings and index.html) plus a selector scan of both
stylesheets. Each hit was confirmed by text search before it went.

JavaScript
- The ten run<Cli>() one-line wrappers and the quickStart() alias: run()
  has dispatched to _runCliMode(mode) since the launcher consolidation and
  nothing called the wrappers except tests, which now call the launcher.
- The Agent Teams panel code that lost its event listeners in February:
  the team tasks panel, the teammate pane window, rebuildTeammateMap and
  the three maps that nothing filled any more.
- Unreferenced methods: redockSession, refreshOrchestratorStatus,
  toggleSubagentPanel, minimizeSubagentWindow,
  openAllActiveSubagentWindows, pickBetterPath, getTodoIcon, deletePreset,
  closeRunSummary, saveSessionOptions, getAgentParentSessionId,
  _isUltracodeAgentMinimized.
- Six unused constants and a few unused locals (an unused frame-time
  computation in the touch scroll loop among them).

CSS
- 62 classes and one id that no markup, script or test names: the old
  settings-item / settings-section layout, the pre-redesign respawn and
  context-settings rows, the existing-wizard card and others. 116 rules
  and about 770 lines. A dead class inside an :is() list only loses that
  alternative; the rule stays.

Checked in a browser against an isolated instance: no console errors on
desktop or phone, a shell session runs, and 96 screenshots (desktop,
tablet and phone; settings, session options, add case, panels) are
pixel-identical before and after, apart from clock times.
