chore(deps): bump axios, react-query, lucide-react, pg (v0.15.1-beta)

Validated dependency updates (Dependabot #41, #42, #43, #48):
- axios 1.16.0 → 1.16.1
- @tanstack/react-query 5.95.2 → 5.101.0
- lucide-react 1.16.0 → 1.17.0
- pg 8.20.0 → 8.21.0

Holding ioredis at 5.10.1: 5.11.1 (#45) breaks the backend build via a
type mismatch with BullMQ's bundled ioredis copy; leave until BullMQ
bumps its pinned ioredis.
