[CLAUDE] CICD+FE-Admin+FE-User: deploy pool-state guard + SlaTimer component

CICD: check app pool state before Stop-WebAppPool (idempotent).

FE: new SlaTimer component with color-coded countdown (emerald/amber/red)
and progress bar. Two variants:
- inline: used in list tables (Inbox, Contracts list x2, MyContracts)
- full: used in ContractDetail card with progress bar + deadline timestamp
