Add core fingerprint operations: enrollment, verification, identification, print listing, print deletion, and storage clearing. New files: - validity_db.h/c: On-chip template database operations — command builders for all DB commands (0x45-0x4B, 0x47-0x48, 0x51, 0x5E, 0x60, 0x62, 0x63, 0x64, 0x68, 0x69, 0x6B), response parsers for DB info/user storage/user/ record value/record children/new record ID, identity builder (UUID→VCSFW binary), finger data builder, and db_write_enable blob accessor. - validity_enroll.c: 31-state enrollment SSM with interrupt-driven finger detection (EP 0x83), capture command orchestration via build_cmd_02(), enrollment session management (create/update/commit), DB record creation (user + finger), and LED glow feedback. - validity_verify.c: 17-state verify/identify SSM with match command dispatching (cmd 0x5E for verify, cmd 0x60 for identify), 6-state list SSM for enumerating enrolled prints via GPtrArray, 8-state delete SSM, and clear_storage stub. Modified files: - validity.h: Added DB header include, 5 new state enums (CalibState, EnrollState, VerifyState, ListState, DeleteState), new struct fields for enrollment/verification/list/delete state, function declarations. - validity.c: Replaced all operation stubs with real implementations, added cleanup for new fields in dev_close, wired all FpDevice methods. - meson.build: Added 3 new source files to driver. - tests/meson.build: Added test-validity-db executable. - tests/validity/custom.py: Updated feature assertions (STORAGE, STORAGE_LIST, STORAGE_CLEAR now enabled). Tests: 29 new unit tests in test-validity-db.c covering all command builders, response parsers, identity/finger data builders, and blob accessor. All 37 tests pass (0 fail, 2 skip).
