Redesign admin sidebar: collapsible categories, icons, role-accurate nav

Regroup the flat 12-link staff sidebar into collapsible category sections
(Content / Moderation / System, with Dashboard and Account ungrouped) and
add a small inline-SVG icon per item. Category collapse state persists in
localStorage and the group holding the active route auto-opens.

Gate each item by role to match server-side enforcement so the sidebar no
longer shows links that would 403: Content is admin/editor, Moderation is
admin/moderator, System (Users, Settings, Hero Editor, Authentication,
Discord Bot, Web Bot Activity) is admin-only. Existing moderator confinement
(Moderation + Account only, plus redirect) is preserved.

Rename "Bot Activity" to "Web Bot Activity" to distinguish the bot-scoring
view from the Discord Bot.
