feat(reports): header actions, single export dialog, date-range presets

- ReportPage drops its own PageHeader (and the back arrow); ReportView
  now optionally renders the header itself (pageHeader prop) with
  export/refresh as its actions. Embedded ReportSection usage is
  unaffected (keeps the inline toolbar next to filters).
- Replace the two xlsx/pdf icon buttons with one Export button opening
  a dialog: format as large icon radio cards, fields as checkboxes
  (select-all toggle), record count (default all, capped per format).
  Export applies the report's current filters and sort.
- Backend: export route accepts fields (whitelisted against the
  report's own columns) and limit; ReportExportService takes an
  optional column subset instead of always dumping every column.
- Fixed a real bug found while wiring this up: runAll() ignored the
  caller's sortBy/sortOrder and always used the report's default sort,
  so exports silently didn't match whatever order was on screen.
- Report daterange filters now use DatePickerInput + the shared
  getDateRangePresets() (Today/Last 7 days/This month/...) instead of
  two bare DateInputs, matching every other date-range filter in the
  app.
- Removed the reports hub grid page. /dashboard/reports now redirects
  to the first report the caller has access to, or /dashboard if they
  have none.
