feat: Expose remaining graphql-java ParserOptions settings in vertx-config.json

[velo]

Follow-up to #2276, which exposed only the four integer limits of graphql-java's ParserOptions. This adds the remaining settings that sit alongside them.

Change

graphQLParserConfig now covers everything ParserOptions.Builder exposes:

"graphQLParserConfig" : {
  "maxCharacters" : 1048576,
  "maxTokens" : 15000,
  "maxWhitespaceTokens" : 200000,
  "maxRuleDepth" : 500,
  "captureIgnoredChars" : null,
  "captureSourceLocation" : null,
  "captureLineComments" : null,
  "readerTrackData" : null,
  "redactTokenParserErrorMessages" : null
}

The five new flags are Boolean, not boolean, and default to null. That is deliberate: graphql-java does not use one value across all parsers. Dumping the 26.0 defaults:

setting	generic	operation	sdl
captureIgnoredChars	false	false	false
captureSourceLocation	true	true	true
captureLineComments	true	false	true
readerTrackData	true	true	true
redactTokenParserErrorMessages	false	false	false

captureLineComments differs between generic and operation parsing, so baking a single primitive default into the config would silently flip operation parsing to true for every deployment. A null flag is left untouched, preserving whatever graphql-java defaults to for the parser being configured; a non-null flag is applied to both. Behaviour is unchanged when the section is absent or left at its defaults.

parsingListener is the one builder setting not exposed — it takes a callback implementation, which cannot be expressed in a config file.

Testing

• GraphQLParserConfigTest — new cases for the flags being applied to both parser defaults, and for unset flags preserving the generic-vs-operation captureLineComments split rather than flattening it.
• ServerConfigTest — the flags deserialize from the config section.
• ServerConfigTemplateTest — template round-trip with the new nullable keys.
• ServerFunctionContainerIT re-run against freshly built :local images, so the server is verified to still start and parse with the new nullable keys present in vertx-config.json.

Full mvn test is green.
