fix(front): remove runtime default-view creation fallback (#21652)

## Problem

`useCreateDefaultViewForObject` was a temporary runtime fallback that
created a view + one view field per field (each with a fresh `v4()` id)
whenever `RecordIndexLoadBaseOnContextStoreEffect` found no view for the
current view id. Because the created view got a fresh id that never
matched the requested `contextStoreCurrentViewId`, the next load missed
again and re-created another duplicate — leaking `core.view` /
`core.viewField` rows without bound (notably during the 2.13.0
cache-first bootstrap window).

#21592 made the fallback idempotent as a stop-gap, but the mechanism is
no longer needed at all: standard/index views are created server-side at
object creation and during standard app installation, so the client
never needs to mint them.

## Change

Remove the fallback entirely:
- Delete `useCreateDefaultViewForObject`.
- In `RecordIndexLoadBaseOnContextStoreEffect`, when no view resolves
for the current id, do nothing and let the loaded views settle (the
effect re-runs once the view is present and loads it).

## Note

This removes the leak at the source for any client running the new
bundle. Clients still on old cached JS will keep creating duplicates
until they reload; the already-leaked rows are being cleaned up
separately via SQL.
