refactor(kilo-pass): inline promo eligibility into getState to reduce DB calls

[markijbema]

Summary

• Inline promo eligibility into the kiloPass.getState response by adding isEligibleForFirstMonthPromo to GetStateOutputSchema, eliminating the need for a separate getFirstMonthPromoEligibility tRPC procedure and its redundant getKiloPassStateForUser DB query.
• Remove the getFirstMonthPromoEligibility procedure entirely and update ProfileKiloPassSection to read promo eligibility directly from getState data.
• This reduces the number of getKiloPassStateForUser DB calls on the profile page from 2 to 1 for users without an active subscription.

Verification

• pnpm typecheck — passes
• pnpm jest -- src/routers/kilo-pass-router.test.ts — 35/35 tests pass, including 2 new tests for isEligibleForFirstMonthPromo (eligible when no subscriptions, ineligible when canceled subscription exists)

Visual Changes

N/A

Reviewer Notes

• The isEligibleForFirstMonthPromo field is placed at the top level of the getState response (alongside subscription) so it's available even when subscription is null.
• The promo eligibility logic is: true when getKiloPassStateForUser returns null (no subscription rows at all), false otherwise (including canceled/ended subscriptions). This matches the prior getFirstMonthPromoEligibility behavior exactly.

File	Line	Issue
packages/trpc/dist/index.d.ts	14741	The checked-in @kilocode/trpc declarations are stale: getState still omits isEligibleForFirstMonthPromo, and the removed getFirstMonthPromoEligibility procedure is still exported. Since packages/trpc/package.json publishes ./dist/index.d.ts, repo consumers will keep seeing the old API surface until this build artifact is regenerated.
