Feature ETP-4609: Fix product grid filter panel bugs

[IrinaUrri]

Jira: https://etendoproject.atlassian.net/browse/ETP-4609

Scope (this repo — schema_forge_core / @etendosoftware/app-shell-core)

This repo owns the generic grid filter component, so it carries the shared fix for bug 1 plus the fully backend-independent bug 3 and bug 4:

• Bug 1 (generic fix): grid filter operator/column rules corrected so invalid operator/column combinations are no longer offered (isNull-type ops hidden on required columns, ghost/non-filterable columns excluded from the operator list).
• Bug 3 / Bug 4: the inSet filter was case-sensitive, causing valid matches to be silently dropped when casing didn't line up; made case-insensitive.

Commits (test-first, per Bug/Pasada1 QA-gated process)

1. Add failing tests for grid filter panel bugs — reproduces bug 1 (bad operator/column combos)
2. Hide isNull ops on required + exclude ghost cols — fixes bug 1
3. Document filter operator/column rules — docs for the bug 1 fix
4. Add failing test for case-sensitive inSet filter — reproduces bug 3/4
5. Make inSet filter case-insensitive — fixes bug 3/4
6. Document case-insensitive inSet filter — docs for the fix

⚠️ Follow-up required before this takes effect for functional windows

This package is consumed by etendo_schema_forge as the published @etendosoftware/app-shell-core dependency (default profile — see docs/repo-topology.md there). These fixes will not reach functional windows outside LOCAL_CORE dev mode until this package is published and version-bumped in etendo_schema_forge. That publish + bump is a known follow-up, out of scope for this PR.
