feat(auth): implement session-based token management with revocation support
Add Session model, SessionService, and SessionRepository to track user login
sessions and enable token revocation on auth-critical events.

- Introduce explicit TokenType (access/refresh) in JWT claims to prevent
  refresh token misuse via access token endpoints
- Add SessionID field to JWT claims, enabling stateless JWT validation
  against revoked sessions
- Replace legacy Auth middleware with RequireAuth/OptionalAuth pipeline
  that validates token type, account status, and session validity
- Implement session revocation on password change, reset, user ban/inactive,
  and explicit logout
- Add Principal cache with active invalidation for banned/role-changed users
- Fix IDOR vulnerability: GetMessagesByCursor now validates currentUserID
  is conversation participant via GetParticipantStrict
- Add group member visibility checks: announcements, group info, member list
  now require group membership
- Simplify Casbin policy: remove g grouping, use r.sub == p.sub matcher
  with globMatch; user_roles table is single source of truth for roles
- Add migration logic to clean legacy casbin g rules and migrate old p rules
  from path-style to admin/<domain> resource naming

// Package middleware 提供路由层中间件。
//
// 注意:旧的 Auth/OptionalAuth 函数已被 auth_pipeline.go 中的
// RequireAuth / OptionalAuth 替代,新版本内置令牌类型校验、账户状态校验与会话校验。
// 路由层应使用 RequireAuth(jwt, idp, cache) 与 OptionalAuth(jwt, idp, cache)。
