chore(web): centralize shared frontend dependency versions

- add a web workspace catalog to manage dependency versions shared by default and classic frontends.
- switch shared dependencies including @lobehub/icons to catalog references and align @lobehub/icons on 5.10.0.
- replace separate frontend Bun lockfiles with a unified web/bun.lock to reduce duplicate maintenance.
