Replace manual resource ID entry with a searchable, filterable resource
picker that uses live WebSocket state. Support selecting multiple
resources (up to 50) for combined fleet reports.
Multi-resource PDFs include a cover page, fleet summary table with
aggregate health status, and condensed per-resource detail pages with
overlaid CPU/memory charts. Multi-resource CSVs include a summary
section followed by interleaved time-series data with resource columns.
New POST /api/admin/reports/generate-multi endpoint handles multi-resource
requests while the existing single-resource GET endpoint remains unchanged.
Also fixes resource ID validation regex to allow colons used in
VM/container IDs (e.g., "instance:node:vmid").
The WearLevel field represents SSD life REMAINING, not wear used:
- 100% = fully healthy (new drive)
- 0% = end of life
Fixed logic to:
- Show critical warning when life <= 10% (not >= 90%)
- Show warning when life <= 30% (not >= 70%)
- Display values in green when healthy (>30% life remaining)
- Rename column from "Wear" to "Life" for clarity
- Add professional cover page with branding and report period
- Add Executive Summary page with health status banner (HEALTHY/WARNING/CRITICAL)
- Add Quick Stats section with color-coded metrics and trend indicators
- Add Key Observations with automated analysis of CPU, memory, disk, and disk wear
- Add Recommended Actions section with prioritized, actionable items
- Add Resource Details page with hardware info, storage pools, physical disks
- Add color-coded tables for alerts, storage, and disk health
- Add performance charts with area fills and proper scaling
- Improve overall visual design with consistent color scheme
- Fix SAML session invalidation to use correct SessionStore method
