Subject: [PATCH] Prioritize user lists syncing during login

Prioritize fetching of block lists, subscriptions, and other user data before loading the main video feed during login.
- In `handleAuthLogin`, stop the existing video feed subscription immediately to free up bandwidth.
- Explicitly await `subscriptions.ensureLoaded(activePubkey)` alongside `userBlocks.seedWithNpubs` before triggering `refreshAllVideoGrids`.
This ensures user context is fully loaded before the heavy feed sync starts, addressing slow sync issues especially with NIP-07.
