test: reduce number of coderdtest instances (#23463)

Consolidates coderdtest invocations in 7 tests to reduce 23 instances to 7 across:
- `TestGetUser` (3 → 1) — read-only user lookups
- `TestUserTerminalFont` (3 → 1) — each creates own user via
CreateAnotherUser
- `TestUserTaskNotificationAlertDismissed` (3 → 1) — each creates own
user
- `TestUserLogin` (3 → 1) — each creates/deletes own user
- `TestExpMcpConfigureClaudeCode` (5 → 1) — writes to isolated temp dirs
- `TestOAuth2RegistrationTokenSecurity` (3 → 1) — independent
registrations
- `TestOAuth2SpecificErrorScenarios` (3 → 1) — independent error
scenarios
