Remove debug logs and UNSAFE/experimental imports

[sugan0tech]

Summary
Remove debug logging and experimental/UNSAFE imports to keep the codebase clean and production-ready.

Context

• src/components/space/EditSpace.tsx contains console.log calls used for debugging.
• Experimental/UNSAFE imports (e.g., UNSAFE_getPatchRoutesOnNavigationFunction, UNSAFE_createClientRoutesWithHMRRevalidationOptOut) appear but are not used.

Tasks

• Remove console.log statements and similar debug output from committed code.
• Delete experimental/UNSAFE imports and any dead code guarded by them.
• Ensure no behavior changes; replace logs with toasts or proper error handling if needed.

Acceptance Criteria

• npm run lint passes without console or unused import warnings in affected files.
• No change in user-facing behavior.
