## Summary
Fixed multiple TypeScript errors that were preventing the production
build from completing on Railway.
## Changes Made
### Nullable Type Fixes
- Fixed `searchParams.toString()` calls with optional chaining (`?.`)
and fallback values
- Fixed `pathname` nullable access in UpdateToastClient
- Added fallbacks for undefined values in translation interpolations
### Type Consistency Fixes
- Fixed recency parameter handling (string from URL, converted to number
internally)
- Removed duplicate local interface definitions for Party and User types
- Fixed Party type mismatches by using global type definitions
### API Route Error Handling
- Fixed error type checking in catch blocks for login/signup routes
- Added proper type guards for axios error objects
### Component Props Fixes
- Fixed RadixSelect.Trigger by removing invalid placeholder prop
- Fixed Toast and Tooltip components by using Omit to exclude
conflicting content type
- Added missing onAdvancedFilter prop to FilterBar components
- Fixed PartyFooter props with required parameters
## Test Plan
- [x] Fixed all TypeScript compilation errors locally
- [ ] Production build should complete successfully on Railway
- [ ] All affected components should function correctly
