fix(memoro/server): resolve all TypeScript strict mode errors

- Add Hono<{ Variables: AuthVariables }> typing to all authenticated route files
- Conditionally spread optional params to satisfy exactOptionalPropertyTypes
- Fix implicit any on catch handlers (err: unknown)
- Prefix unused _userId param in space service declineInvite
- Remove unused imports (handleTranscriptionCompleted, updateMemoProcessingStatus)
- shared-hono/credits: prefix unused _operation param in validateCredits
