feat(dashboard): role-aware hotel BI home and report gallery

[telivity-otaip]

Summary

Turns the staff dashboard and Reports page into role-aware hotel BI that managers and ops leads will actually open every day.

Home dashboard (/)

• Permission-based personas: Manager flash, Revenue (pace/pickup), Accounting (ledgers/aging), Front Office, Housekeeping — resolved from effective property permissions (demo/auth-off → full manager view)
• Atmospheric BI hero with Today / Yesterday / 7D / 30D / MTD period chips
• KPI cards with sparklines, vs-prior-day deltas, threshold tinting, and drill-through into Reports
• Exception strip: open folio balances, night-audit health, OOO, pending revenue decisions
• Surfaces API fields that were previously unused (revenue mix, payments, outstanding balances, audit status)
• Portfolio mode gets the same visual language with property drill-down

Reports (/reports)

• Report gallery (flash / rooms / demand / accounting) with favorites — replaces the dropdown-first tool
• Richer charts and ledger panels; CSV export links for daily revenue + trial balance
• Deep links (?report=…) from Accounting still work

Implementation notes

• Stays on existing Recharts + Telivity tokens (no new chart deps)
• No new API endpoints — builds on /v1/reports/*, rooms, reservations, housekeeping, A/R aging, agents
• Unit tests for persona resolution and period range helpers
• pnpm --filter @telivityhaip/dashboard typecheck passes; dashboard package builds

Test plan

• Open / with auth off (or GM) → Manager flash with KPIs, exceptions, mix charts, trend/pace
• Simulate front-desk permissions → ops activity KPIs, no finance report calls required
• Simulate housekeeping → task/urgent board with link to /housekeeping
• Simulate revenue manager → pickup + pace + occupancy trend primary
• Simulate accounting → ledger health + A/R aging buckets
• Portfolio mode → property scorecard + revenue bars
• /reports gallery select each report type; favorites persist; CSV links for daily revenue / trial balance
• Deep link /reports?report=trial-balance still opens that report
