Security UI improvements

[glebfox]

1. Custom filer should use flowBox for filter fields, so they are displayed on the next line if nit enough space

2. Not all columns values have localization, e.g. Type, Action, Source

3. (Code) Create Entity resource policy - actions must be presented with CheckBoxGroup instead of separate CheckBoxes

4. All Create policy screens have to check unsaved changes. Currently only Specific Policy and GraphQL Policy do that.

5. GraphQL Policy is edited (not created) with the DefaultPolicyEditor instead of its own

6. Row-level policy - Dialog buttons must be aligned to the left as all dialog buttons do. Documentation link can be aligned to the right. Also it's worth implementing docs link using the Link component instead of LinkButton with programmatic page opening

7. Action field for Predicate Policy for Annotated Class Row Level Role is editable and can produce unsaved changes

We should do all items except 2 (Not all columns values have localization, e.g. Type, Action, Source)
