fix(graphql): build filter args from parameters

[soyuka]

What

Unifies GraphQL field-argument generation in FieldsBuilder so filters declared via #[QueryParameter] reach full parity with the legacy #[ApiFilter] path.

Problem

FieldsBuilder built GraphQL arguments from two divergent code paths:

• legacy Operation::getFilters() (#[ApiFilter]) — supported nested-collection args (colors(prop:)) and operator forms;
• canonical Operation::getParameters() (#[QueryParameter]) — flattened dotted keys (colors.prop) into root args and never exposed ComparisonFilter operator forms.

So migrating fixtures from #[ApiFilter] to QueryParameter (the 4.4/bc-filter work) silently dropped nested-collection and operator arguments over GraphQL. The legacy FilterTest suite only stayed green because DummyCar still uses #[ApiFilter].

Change

One intermediate arg-tree (#name/#list/#nonNull markers) feeds one converter, replacing getFilterArgs/getParameterArgs/parameterToObjectType/getParameterType/mergeFilterArgs/convertFilterArgsToTypes. Both filter and parameter sources feed the same tree.

QueryParameter parity:

• nested collection args (colors(prop:)) from the related resource's own parameters via the existing depth recursion (also fixes a latent bug where parameter args were sourced from the root operation instead of the resource operation);
• operator forms (gt/gte/lt/lte/ne) derived from JsonSchemaFilterInterface::getSchema() instead of the empty deprecated getDescription();
• scalar leaf types from the parameter's native type (an int property yields GraphQL Int).

Sort filters are list-shaped (order: [{...}]) because GraphQL input-object fields are unordered and cannot preserve multi-key ordering, whereas every other bracketed filter (search/comparison/date/exists) stays a single input object. This is recognized through a new backend-agnostic ApiPlatform\Metadata\SortFilterInterface, implemented by the Doctrine ORM/ODM SortFilter and the Laravel OrderFilter — so FieldsBuilder depends only on Metadata, not on any persistence layer.

Runtime is unchanged — ReadProvider/ParameterProvider/FilterExtension/ParameterExtension already apply both paths.

Tests

New ParameterFilterParityTest + GraphQlFilteredResource(Color) fixtures (ORM + ODM) declare DummyCar-equivalent filters via QueryParameter and assert nested search, ComparisonFilter operators (gt: 10 → Int), root exact and order list shape — failing before, green after. Legacy DummyCar/FilterTest left untouched as the BC anchor.
