chore: update dependencies to latest minor/patch versions

Update dependencies and devDependencies to their latest compatible versions:

Dependencies:
- body-parser: 2.2.1 → 2.2.2
- decimal.js: 10.5.0 → 10.6.0
- express: 5.1.0 → 5.2.1
- msw: 2.8.4 → 2.12.7

Dev Dependencies:
- @biomejs/biome: 2.3.7 → 2.3.11
- @changesets/cli: 2.29.7 → 2.29.8
- @types/body-parser: 1.19.5 → 1.19.6
- @types/express: 5.0.5 → 5.0.6
- @types/morgan: 1.9.9 → 1.9.10
- @types/qs: 6.9.11 → 6.14.0
- @vitest/coverage-v8: 4.0.13 → 4.0.16
- fishery: 2.2.3 → 2.4.0
- supertest: 7.1.4 → 7.2.2
- tsdown: 0.16.8 → 0.18.4
- vitest: 4.0.13 → 4.0.16

Changes:
- Update type signatures for ParsedQs to handle new union type from @types/qs
- Update biome schema version to 2.3.11
- Add missing ctMock.clear() cleanup in payment.test.ts (boy scout rule)

All tests passing. No breaking changes.

Note: Some intermittent test flakiness remains (pre-existing issue unrelated
to these updates).
