feat: implement Phase I — Rich Data Experience (7 features)

Phase I components:
- I.1: InlineEditCell — click-to-edit cells in grid view
- I.2: BulkActionBar + useBulkActions — bulk delete, update, change owner
- I.3: SavedViewsPanel + useSavedViews — persist filter configs per object
- I.4: Enhanced RelatedList section on record detail
- I.5: CloneRecordDialog — duplicate records with field selection
- I.6: CsvImportDialog + CsvExportButton + useCsvOperations — CSV import/export
- I.7: LookupAutocomplete + useLookupSearch — async search for related records

New hooks: useInlineEdit, useBulkActions, useSavedViews, useLookupSearch, useCsvOperations
Updated pages: object-list.tsx (bulk actions, saved views, CSV), object-record.tsx (clone)
Tests: 207 passing (30 new tests added)
