fix(codegen): collect input types referenced by table field arguments

[pyramation]

Summary

Split from #1200 (Issue 1 only), rewritten with an improved approach.

Problem: Input types referenced only by table-field arguments (e.g. FooBulkUploadFileInput on bucket computed fields like requestBulkUploadUrls(files: [FooBulkUploadFileInput!]!)) were inlined into *Select types via typeRefToTs but never registered for generation — leaving the referenced Input interfaces undefined in the output.

Approach (differs from #1200): Instead of adding a standalone collectFieldArgInputTypes function as a third parallel collector, this extends the existing collectInputTypeNames() to optionally accept tables and scan their computed-field args. This keeps one function and one code path for all input type collection from args.

The fix is applied at two levels for defense-in-depth:

1. Orchestrator (index.ts): passes tables to collectInputTypeNames(allOps, tables) so field-arg types flow through the normal pipeline
2. generateInputTypesFile: also merges field-arg types internally, so direct callers (including tests) get correct behavior without needing to pre-collect

Files changed:

• graphql/codegen/src/core/codegen/orm/input-types-generator.ts — extended collectInputTypeNames signature + defense-in-depth merge
• graphql/codegen/src/core/codegen/orm/index.ts — passes tables to collectInputTypeNames
• graphql/codegen/src/__tests__/codegen/input-types-generator.test.ts — 2 regression tests (end-to-end generation + unit test of collectInputTypeNames)

Review & Testing Checklist for Human

• Run codegen against a schema with bucket tables and verify the BulkUploadFileInput types appear in generated output
• Verify no duplicate type declarations when a field-arg type is also referenced by a custom operation

Notes

This replaces the original #1200 Issue 1 implementation. The key difference: no new standalone function — just extends the existing collectInputTypeNames with an optional tables parameter, following the principle of one collection path rather than parallel collectors.
