chore: check in pending work — queue preferences, QBO AR diagnostics, mobile engagement fixes, ops scripts

Bundles several in-progress efforts that were sitting uncommitted:
- User queue-preferences (migration 087, API route, popover component)
- QBO invoice soft-delete (migration 088) and AR diagnostics route
- Dashboard/mobile engagement route and page adjustments
- Docker Compose log-rotation config
- One-off ticket/RMM investigation scripts (scripts/)
- Planning docs: phase verification/pattern notes, mobile shell design spec
- .gitignore: exclude local scratch financial/inventory data and Claude Code
  worktree/local-settings runtime state (never meant for version control)
