[Console] Simplify RBAC to fixed Admin and Editor user types

[shangeyao]

Background

StreamPark currently ships a configurable RBAC model based on roles, role-menu bindings, team membership, and a custom @Permission aspect for resource-level checks. This adds significant operational and maintenance overhead for most deployments, where only a small set of fixed capabilities is needed.

Proposal

Simplify authorization to two built-in user types stored on t_user.user_type:

• Admin — full access (*)
• Editor — fixed permission set for job and development resources (app/sql/project/resource/etc.)

Scope

1. Remove role/member/team management APIs, entities, mappers, and UI pages
2. Derive Shiro roles and permissions directly from UserTypeEnum
3. Remove the legacy @Permission annotation and PermissionAspect
4. Keep API authorization via Shiro @RequiresPermissions
5. Add MySQL/PostgreSQL 3.0.0 upgrade scripts to migrate legacy team-admin membership and drop obsolete RBAC tables
6. Update frontend permission checks and remove obsolete E2E cases

Motivation

• Reduce complexity for operators and contributors
• Make authorization behavior predictable and easier to test
• Align with StreamPark 3.0 simplification goals

Notes

Team identifiers remain in the data model for existing resources, but team/member/role administration is removed from the console.
