feat: replace hardcoded price map with real-time Jupiter API v3 (P0-06)

[EKF0]

This pull request integrates the public Jupiter Price API v3 to fetch dynamic, real-time token valuations and prices for connected wallets inside the portfolio resolver. It also syncs other completed local changes and adds full Vitest unit testing coverage.

Changes:

1. Replaced the static, hardcoded price map with dynamic bulk fetching from Jupiter Price API v3 in lib/solana/balances.ts.
2. Created a 30-second in-memory pricing cache to optimize request load and prevent rate limit issues.
3. Implemented robust fallback logic that reverts to stale cache or hardcoded values upon network errors.
4. Added Vitest unit tests in test/price-service.test.ts validating bulk fetching, errors, and enrichment logic.
5. Synchronized outstanding local improvements across app shell, navigation, Creator Lab, and database schemas.
