**Title:** Validation Checkpoint 2: Read Operations

**Status:** done

**Dependencies:** 15, 16, 17, 18

**Priority:** high

**Description:** Validate Phase 2 completion by testing all read/query operations for users, numbers, and locations. This checkpoint gates entry into Phase 3 (Write Operations).

**Details:**

**Validation Criteria:**
- [x] `users list` returns paginated results with all fields
- [x] `users show` returns complete voice configuration
- [x] `numbers list` returns inventory with status
- [x] `numbers search` finds numbers by pattern
- [x] `locations list` reads from CSV correctly
- [x] Staleness warning displayed for old CSV
- [x] --json output is valid JSON for all commands

**Test Execution:**
1. Run `users list` with --licensed, --assigned filters, verify pagination
2. Run `users show <upn>` and verify all voice config fields displayed
3. Run `numbers list` with --status, --type, --city filters
4. Run `numbers search "206*"` and `numbers search "*1234"` pattern matching
5. Run `locations list` and verify CSV data displayed
6. Test with CSV older than 30 days, verify staleness warning appears
7. Run all commands with --json and validate JSON output with jq

**Success Criteria:** All read operations return correct data, filters work, JSON output is valid, staleness warnings appear when appropriate.

**Test Strategy:**

Integration tests against test tenant with sample users, numbers, and location CSV data. Verify output formats and filtering.

| `users list --assigned` | PASS | Client-side filter (Graph API limitation) |
| `users list --unassigned` | PASS | Client-side filter works |
| `users show <upn>` | PASS | Returns complete voice config with all policies |
| `numbers list` | PASS | Returns inventory with status |
| `numbers list --status` | PASS | Filter by assignment status |
| `numbers list --type` | PASS | Filter by number type |
| `numbers list --city` | PASS | Client-side city filter |

### Issues Found & Fixed

1. **AccountType enum missing `ineligibleUser`**
   - Graph API returned `accountType: 'ineligibleUser'` which wasn't in our enum
   - Fixed: Added `INELIGIBLE_USER = "ineligibleUser"` to `AccountType` enum
   - File: `src/teams_phone/models/user.py`

2. **assigned filter not supported by Graph API**
   - Graph API returned error: "The method or operation is not implemented" for `telephoneNumbers/$count` filter
   - Fixed: Changed to client-side filtering for assigned/unassigned status
   - File: `src/teams_phone/services/user_service.py`

3. **Unit tests updated for client-side filtering**
   - Updated tests to verify client-side filtering behavior
   - File: `tests/unit/test_user_service.py`

### Files Modified

- `src/teams_phone/models/user.py` - Added `INELIGIBLE_USER` to AccountType enum
- `src/teams_phone/services/user_service.py` - Client-side filtering for assigned status
- `tests/unit/test_user_service.py` - Updated 3 tests for client-side filtering

### Verification

- All 29 user service unit tests pass
- All 845 unit tests pass
- Linting passes (ruff check)
