chore(mise): generate schema clients before typechecking

[roziscoding]

What does this PR do?

Makes mise run typecheck generate the schema clients it depends on.

packages/schemas/src/generated/ is gitignored, so on a fresh checkout typecheck runs against clients that don't exist yet and fails with ~13 errors:

apps/backend/src/lib/servers/arr/radarr.ts(1,55): error TS2307: Cannot find module '@jack/schemas/radarr/types'
apps/backend/src/lib/servers/arr/radarr.ts(67,38): error TS7006: Parameter 'l' implicitly has an 'any' type
packages/schemas/src/index.ts(1,30): error TS2307: Cannot find module './generated/radarr/types.gen'
...

Nothing is wrong — mise run clients just hasn't run. But the errors point at real source files and read like a regression in whatever you last touched, which is a bad first five minutes on a new machine. (It cost me exactly that this week.)

The dependency goes on typecheck:backend and typecheck:workspace rather than the typecheck aggregate, because those are the two tasks that actually consume the generated types — so running either directly is fixed too, not just the umbrella task. typecheck:ui doesn't touch them and is left alone.

It depends on clients:generate rather than clients, which skips the rm -rf that clients does first. Generating over existing output is idempotent, so repeating it on every typecheck costs ~350 ms per schema against checked-in *.openapi.json files, with no network and no wiping of files that were already fine.

Checklist

• Commits follow Conventional Commits
• Commits are signed (GitHub enforces this — unsigned commits are rejected)
• mise run lint:fix was run and its output is committed (no changes)
• mise run test passes — unaffected by this change; bun test never needed the generated clients. mise run test:e2e not run: no Docker in the dev environment.
• Docs updated if behavior or configuration changed — n/a, task wiring only

Verification

Wiped packages/schemas/src/generated/ and confirmed every entry point recovers on its own:

• cold mise run typecheck — exit 0, and clients:generate ran once for both dependent tasks (mise dedupes the shared dependency)
• warm mise run typecheck immediately after — exit 0, so regenerating over existing output is safe
• mise run typecheck:backend on its own — exit 0

• Adds clients:generate as a dependency of typecheck:backend.
• Adds the same dependency to typecheck:workspace.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
