* [Protocol] Add moderation investigation commands

Adds the protocol layer for the moderation investigation suite:
- Command_GetUserSessions/GetUserAlts/GetModeratorLastLogins/ResetUserPassword/RemoveUserAvatar (1013-1017)
- Response extensions 1215-1219 with ServerInfo messages for sessions, alts, and staff logins
- last_login on Response_ReportUserInfo and warning_il on Response_WarnList

Took 2 minutes

* [Utility] Add warning categories parser with infraction levels

Parses the server's 'officialwarnings' setting (comma-separated, optional
'|IL' suffix) into WarningCategory structs so the client can display the
infraction level of each warning category. Includes GTest coverage.

* [Server] Add moderation investigation tools

Implements the server side of the moderation suite:
- getUserSessions/getUserAlts/getModeratorLastLogins/removeUserAvatar DB methods
- Handlers for all five new commands with audit records (PASSWORD_RESET,
  REMOVE_USER_AVATAR); password resets return a generated temporary password
- cmdGetWarnList now reports per-category infraction levels from the
  officialwarnings setting; cmdReportUserInfo reports last_login
- Update servatrice.ini.example with the warning taxonomy
- Password/avatar mutations report RespNameNotFound when the user does not exist

* [Client] Add moderation tab with investigate, password reset, and avatar removal

- New Moderation tab: search a user to show account info, alternate
  accounts, login sessions, and staff last logins; actions to reset the
  user's password (shows the generated temporary password) and remove the
  user's avatar
- 'Investigate user' entry in the user context menu opens the tab pre-loaded
  for that user
- Warning dialog shows the infraction level of each warning category
- Tab wired into TabSupervisor with a moderator-gated menu action, shortcut,
  and tabs.ini persistence (default closed)

* [Server/Client/Protocol] Address PR #7091 review: security, bug, and perf fixes

Security:
- Promote RESET_USER_PASSWORD to admin-only dispatch (was moderator-accessible)
- Reject password reset on users with equal/higher privilege than caller
- Notify affected user via Event_NotifyUser::CUSTOM when password is reset
- Add server-side category whitelist for reports
- Drop reporter name fallback in comment/details authorization (ID-only)
- Force password change: new DB column + login enforcement + client disconnect

Bugs:
- XSS via QTextEdit::append() → insertPlainText() in report tab and utils
- allNotified initialized to true even with empty recipients list
- Warning combo box: use currentData() instead of baked-in display text
- Report resolution now records who resolved (resolved_by column + audit)

Performance:
- IP-correlation subquery: add 6-month window + LIMIT 200
- getUserSessions: clamp limit to 500

Non-blocking:
- Palette-aware colors in report_utils.cpp (dark/light mode)
- Report list pagination: offset/limit fields + total_count in response
- SessionCommand enum gap comment for reserved values 1201-1203

Schema: 36→37 (force_password_change), 37→38 (resolved_by)
