fix: resolve Biome linting issues

[braden-w]

Fixes Biome linting warnings that were causing the quality check to fail.

Changes:

• Prefix unused opts parameter with underscore in apps/api/src/index.ts
• Replace any types with unknown for better type safety in apps/sh/src/lib/client/client/

Issues fixed:

• lint/correctness/noUnusedFunctionParameters in apps/api/src/index.ts:53
• lint/suspicious/noExplicitAny in apps/sh client files

This improves code quality and type safety while resolving CI failures.
