• Closes Skill-Based Issue Filtering #2

🎯 Rationale

• Current issue matching was limited and not flexible enough.

• Users couldn’t filter issues by skills/keywords, making discovery harder.

• Theme consistency across dark/light mode was inconsistent.

• This PR improves backend issue retrieval and frontend filtering/UI, creating a smoother developer experience.

📝 Summary of Changes

Backend

• Added load_model() function for FAISS model and initialized it on app startup.

• Expanded GitHub search query to include title, body, and comments (beyond labels).

• Configured session middleware cookie (issuematch_session) with proper attributes.

• Improved error handling and logging in auth.py and faiss_search.py.

Frontend

• New Component: IssueFilter – filter issues by user skills and predefined keywords.

• Integrated IssueFilter into IssuesList with dynamic queries.

• Improved error state when user is not logged in (shows login prompt).

• Extended API timeout from 15s → 25s for reliability.

• Updated styling for skills page, skills test, and welcome screen for consistent dark/light themes.

🔧 Technical Details

• No new external dependencies added.

• Refactored FAISS model loading for performance and maintainability.

• UI uses existing context (useAuth) and Firebase integration.

• Purely additive frontend feature (IssueFilter) – no breaking changes to existing flows.
