Add staff Players directory and player profiles

[ryanbarlow97]

Stacked on #91 (backend). Merge #91 first, then retarget this PR to main.

Summary

• The staff panel gains Accounts and Players tabs.
• /admin/players: a searchable list showing each player's Minecraft name, Discord @, characters, staff role badge and last seen ("Seen just now" while their pings are fresh).
  • Search by Minecraft name (including past names), Discord name, character, UUID or Discord id.
  • Sort by last seen, Minecraft name or Discord name.
  • Search, sort and page are kept in the URL.
  • On phones, the Discord name moves under the player's name and the Characters column is hidden.
• /admin/players/[uuid]:
  • name, UUID, past names, first and last seen;
  • Discord link (including left-Discord grace) and website role;
  • characters;
  • sessions, 20 at a time;
  • recent activity: the last 20 actions, with kind filters (Blocks, Kills, Containers, Items, Skills, Commands, Logins, …) and Load more. Kill victims link to their own profile.
• When a sparse filter stops at the scan limit, the page says "Searched back to …" and offers "Search further back".
• Busy, timed-out or failed pages keep what is already shown and offer Try again from the same point. Changing the filter never mixes in the old filter's cursor.
• Admins and the owner also see a Chat filter, chat lines and full commands (marked when cut short), with a note that these views are logged. Moderators' view is unchanged.
• The sign-in, forbidden and unavailable notices are shared with the existing Accounts page (StaffGate).

Testing

• npx vitest run: 145 files, 1,828 tests pass, plus 3 new pagination regression tests that fail on the earlier code. next build succeeds.
• Ran locally against a copy of Dev's CoreProtect data (339 players) as an Owner account. Directory, search, profile and mobile views were checked in Chromium.

Reviewed by a second agent (Astra), whose two pagination findings are fixed here.

📝 Summary

Summary by CodeRabbit

• New Features
  • Added an admin player directory with debounced search, sorting, pagination and shareable URL state.
  • Added player profiles showing account links, characters, sessions and recent activity, with filtering and pagination.
  • Added navigation between admin accounts and players, plus clear access and availability messages.
• Bug Fixes
  • Improved handling of failed requests, retries and changing filters so outdated results are not shown.

Walkthrough

The admin interface adds player directory and profile pages. New API functions provide player, session and activity data. Shared navigation and staff-gate components support the admin pages.

Changes

Admin player tools

Layer / File(s)	Summary
Player API contracts and formatters frontend/lib/admin/api.ts, frontend/lib/admin/time.ts	Adds player directory, profile, session and activity types and requests. Adds CoreProtect status messages, sort parsing and time formatters.
Staff navigation and gate messages frontend/app/components/admin/AdminNav.tsx, frontend/app/components/admin/StaffGate.tsx, frontend/app/components/admin/AdminPanel.tsx, frontend/app/admin/page.tsx	Adds Accounts and Players navigation with active-page state. Adds shared staff-gate classification and messages, which AdminPanel now uses for non-ready states.
Player directory frontend/app/admin/players/page.tsx, frontend/app/components/admin/PlayersDirectory.tsx, frontend/app/components/admin/PlayersDirectory.test.tsx	Adds directory search, sorting, pagination and URL query-state updates. Tests cover displayed results, requests, navigation and errors.
Player profile, sessions and activity frontend/app/admin/players/[uuid]/page.tsx, frontend/app/components/admin/PlayerProfile.tsx, frontend/app/components/admin/PlayerProfile.test.tsx	Adds a player profile with session and activity pages, filters and retry handling. Tests cover profile data, pagination, filters and errors.

Merge Risk: 🔵 Low · up to 99fb7

Switching between player profiles can temporarily show the previous player’s details or sessions. Fix the profile transition before merging, or accept this bounded staff-view risk.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 99fb7

The new views retain server-enforced staff authorization and do not grant additional privileges. Risk is low, but player-specific history isolation during profile navigation depends on lifecycle behavior that was not fully established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The relevant exposure is the player data returned by the configured backend’s directory and UUID-addressed history operations. The authorization model permits mod, admin and root roles rather than restricting staff to their own player record; that scope predates this PR.

Security Findings and Attack Paths

• inferred — Direct navigation and caller-controlled query, UUID, filter or cursor values do not bypass the inspected authorization boundary. Every player handler delegates through the same capability guard. Existing tests demonstrate anonymous directory denial and player-role directory and activity denial; no unauthorized disclosure was established by this review.

Trust Boundaries and Controls

• observed — The backend remains authoritative: it resolves the current user, checks staff status and view_players, then invokes data access. StaffGate presents failures rather than granting access. Client requests disable caching, and successful backend player responses pass through the no-store helper.

Resilience and Maintainability Implications

• observed — PlayerProfile rejects old profile completions but retains its loaded state while another UUID is requested. Sessions does not reset UUID-owned rows or guard stale completions; Activity guards completions but does not explicitly clear rows on UUID changes. Route remounting could isolate these states, so the inspected source alone does not establish cross-player contamination.

Hardening Proposals

• proposed — Make profile-history ownership explicitly UUID-scoped through a remount boundary or state invalidation and request guards. Validate pending-request and failure transitions between two profiles so staff data provenance does not depend on implicit routing behavior.

- Around line 175-201: Update the route that renders PlayerProfile to decode the
UUID once and pass it as both the component key and uuid prop. This remounts
PlayerProfile and its child panels when navigation changes the UUID, preventing
the previous profile and stale session responses from affecting the new one.
