fix: mark repository handler parameters with NamedDependency

[lesnik512]

Summary

Litestar 2.23+ emits a LitestarDeprecationWarning for every dependency parameter that is resolved by name without an explicit marker ("Inferred dependencies will stop working in Litestar 3.0"). The test suite printed 216 of these: 8 handlers times 27 app builds.

• Annotate the decks_repository / cards_repository handler parameters in app/api/decks.py and app/api/cards.py with litestar.di.NamedDependency[...] (Litestar 2.24.0, as pinned in uv.lock). The dependency registration in app/application.py via modern_di_litestar.FromDI is unchanged; NamedDependency only marks the parameter as injected by name.
• Ignore ruff's TC rules globally instead of per-file / inline noqa: TC00x. Litestar resolves handler annotations at runtime and modern-di reads creator annotations, so moving those imports into TYPE_CHECKING blocks (which ruff --fix with unsafe fixes would do) breaks app startup. This replaces the app/resources/*.py per-file ignore and the six inline noqa comments in app/api/.

Test plan

• just test: 31 passed, 0 warnings (was 31 passed, 216 warnings)
• just lint: ruff and ty clean
