Fix batch update optimistic and prevent accidental mass-update (#17213)

## Problem
- ⚠️ Multi-edit could silently update ALL records of an object with no
undo, no ctrl-z
- After a batch update the table showed stale data —
`useIncrementalUpdateManyRecords` had no explicit `findMany` refetch and
`skipOptimisticEffect` was missing
- Clicking inside the side panel deselected all kanban cards —
`RecordBoardClickOutsideEffect` uses `refs:[]` and the side panel had no
`data-click-outside-id`
- Clicking a currency/select dropdown inside the panel also triggered
deselection — `FloatingPortal` renders outside the side panel DOM,
bypassing the click-outside-id exclusion
- An empty selection silently matched every record —
`computeContextStoreFilters` returned `undefined` filter when
`selectedRecordIds` was `[]`

## Fix
- Table refreshes correctly after batch update —
`useRefetchFindManyRecords` explicitly refetches `FindMany<Object>`
queries; `useIncrementalUpdateManyRecords` adds `skipOptimisticEffect:
true` and calls it in `finally`
- Clicking the side panel no longer deselects kanban cards —
`SidePanelForDesktop` carries `data-click-outside-id`;
`RecordBoardClickOutsideEffect` +
`RecordTableBodyFocusClickOutsideEffect` exclude it
- Clicking dropdowns inside the panel no longer deselects either —
`ParentClickOutsideIdContext` propagates the side panel ID into
`FloatingPortal` content via `DropdownInternalContainer`
- Empty selection can no longer match all records —
`computeContextStoreFilters` returns `{ id: { in: [] } }` instead of
`undefined`
- Apply is disabled with no selection; a confirmation modal shows the
count + no-undo warning before executing —
`UpdateMultipleRecordsContainer`

## Not included
- Undo / snapshot restore — requires backend changes, out of scope

## Blast radius
- `ParentClickOutsideIdContext` touches `DropdownInternalContainer` (207
`<Dropdown>` usages). `parentClickOutsideId` is `undefined` everywhere
outside the side panel → attribute not rendered → zero behavioral change
for existing consumers.
