feat(explorer): dynamic feeds, wallet SSR alignment, and detail pagination

Align wallet SSR with report token-list, dedupe featured v1 tokens, refresh home and wallet snapshots on a 60s cadence, and drive vanilla SPA chain add/watch from API metadata. Add shared pagination/tabs for address, token, and transaction pages, extend token aggregation helpers, and harden stats API with tests and health checks.
