feat: add profile lifecycle + password/lock tests (56 total)

- test/profiles.test.js: create, rename, switch, delete profiles (14 tests)
- test/password-lock.test.js: set/change/remove password, lock/unlock,
  auto-lock timeout, wrong password rejection (17 tests)
- Full lifecycle tests: create → rename → switch → delete
- Full lifecycle tests: set → lock → fail → unlock → change → remove
- All 56 tests pass in 80ms
