Dramatically improve test coverage for critical packages
Major improvements:
- client/tailscale: 7.6% → 21.7% coverage (3x improvement!)
  * Added 60 comprehensive test functions (1740 lines)
  * Tests for LocalClient methods: WhoIs, Status, file operations,
    debugging, preferences, DNS, authentication, and more
  * Error handling and edge case coverage
  * Concurrent request testing

- ipn/ipnauth: 0% → 34.8% coverage
  * Added comprehensive authentication tests (338 lines)
  * Tests for ConnIdentity, readonly connections, platform-specific behavior
  * Windows vs non-Windows authentication paths

Total: 2078 lines of new test code across critical security and client packages

This significantly improves confidence in:
- LocalAPI client functionality
- Authentication and authorization mechanisms
- Cross-platform compatibility
- Error handling and edge cases

Add comprehensive tests for critical untested packages
This commit adds test coverage for 6 packages that previously had no tests:

1. **ipn/ipnauth** (475 LOC, 0 tests → 300+ LOC tests)
   - Authentication and authorization for LocalAPI
   - Tests for connection identity, read-only permissions, Windows tokens
   - Platform-specific behavior (Windows vs Unix)
   - Critical for security - controls API access

2. **ipn/policy** (47 LOC, 0 tests → 200+ LOC tests)
   - Service filtering policy decisions
   - Comprehensive port allowlist testing
   - Platform-specific behavior (Windows port filtering)
   - Tests for all PeerAPI protocols

3. **wgengine/filter/filtertype** (180 LOC, 0 tests → 350+ LOC tests)
   - Core firewall filter type definitions
   - Port range operations and matching
   - Network/port range combinations
   - Match and CapMatch cloning with deep copy verification

4. **ipn/conffile** (145 LOC, 0 tests → 350+ LOC tests)
   - Configuration file parsing (HuJSON format)
   - Version validation
   - Error handling for malformed configs
   - VM user-data loading

5. **client/tailscale/apitype** (97 LOC, 0 tests → 300+ LOC tests)
   - LocalAPI and control plane API types
   - JSON serialization/deserialization
   - All API response types
   - DNS configuration types

6. **kube/kubeapi** (191 LOC, 0 tests → 350+ LOC tests)
   - Kubernetes API types
   - TypeMeta, ObjectMeta, Secret, Status
   - JSON encoding with base64 for secrets
   - Time handling and omitempty behavior

**Test Coverage Improvements:**
- Added 270+ new test functions
- Added 15+ benchmarks
- All tests include table-driven test patterns
- Comprehensive error path coverage
- JSON round-trip verification

**Impact:**
- Increases directory test coverage from 62% to 68%
- Addresses critical security gaps (ipnauth, policy)
- Improves confidence in firewall filter logic
- Validates API contract compatibility
