fix(api): prevent IDOR in TenantNamespace Get and Watch handlers (#2471)

## Summary

Fixed two IDOR (Insecure Direct Object Reference) vulnerabilities in the
TenantNamespace API handlers that allowed authenticated users to access
metadata of tenant namespaces without proper authorization checks.

## Changes

### New optimized function: hasAccessToNamespace()
- Lists RoleBindings **only in the target namespace** instead of all
cluster RoleBindings
- Used by Get() and Watch() for single-namespace access checks
- Order of magnitude faster than the previous approach

### Get() handler
- Uses `hasAccessToNamespace()` for efficient authorization
- Returns `NotFound` instead of `Forbidden` to prevent tenant
enumeration
- Now correctly enforces RoleBinding-based access control

### Watch() handler  
- Uses `hasAccessToNamespace()` for per-event authorization
- Logs authorization errors with klog for security audit
- Events for unauthorized namespaces are silently filtered out
- Ensures users only receive watch events for namespaces they have
access to

### Additional fixes
- Fixed ServiceAccount subject handling when namespace is empty
(defaults to RoleBinding namespace)
- Added proper error logging in Watch handler

## Performance Impact

| Handler | Before | After |
|---------|--------|-------|
| List() | List all RoleBindings × 1 | No change  |
| Get() | List all RoleBindings × 1 | List RoleBindings in 1 namespace 🚀
|
| Watch() | List all RoleBindings × N events | List RoleBindings in 1
namespace × N events 🚀 |

**For Watch with 100 events:**
- Before: 100 × (all cluster RoleBindings) = catastrophic
- After: 100 × (1-5 RoleBindings in namespace) = fast + cached by
controller-runtime

## Security Impact

**Before**: Any authenticated user could:
- Read metadata (labels, annotations, creation time) of any `tenant-*`
namespace via `Get()`
- Stream all tenant namespace events via `Watch()`, including
creation/modification/deletion

**After**: Users can only access tenant namespaces they have explicit
RoleBindings for, matching the behavior of the `List()` handler.

## Testing

Manually verified:
- Users can only `get` their own tenant namespaces
- Users can only `watch` events for their own tenant namespaces
- Unauthorized access returns `NotFound` (not `Forbidden`) to prevent
enumeration
- `List()` behavior remains unchanged and consistent with `Get()` and
`Watch()`
- Authorization errors are logged for security audit

## Checklist

- [x] Code follows project style and conventions
- [x] Security vulnerability is fully mitigated
- [x] Authorization logic is consistent across List/Get/Watch handlers
- [x] Performance optimized per feedback from @timofei.larkin
- [x] Error logging added for security audit
- [ ] Unit tests added (can be done in follow-up PR)

## Summary by CodeRabbit

* **Bug Fixes**
* Enforced per-namespace access control for Get and Watch; inaccessible
namespaces return Forbidden or NotFound as appropriate
* Forwarded field/label selectors to upstream watches and added
defensive filtering to skip inaccessible events (logged)
* Improved ServiceAccount subject namespace fallback and
privileged-group bypass

* **Tests**
* Added security tests covering RoleBinding subjects, groups, privileged
bypasses, ServiceAccounts, and access-denied behaviors
