fix(jooq): resolve DSLContext injection ambiguity

[graemerocher]

Summary

• split the internal jOOQ JDBC and R2DBC configuration beans into distinct types
• create separate DSLContext beans and make the R2DBC-backed DSLContext primary when both are present
• add a focused regression spec covering default DSLContext injection with JDBC and R2DBC together

Verification

• ./gradlew :micronaut-jooq:test --tests 'io.micronaut.configuration.jooq.DslContextFactorySpec'\n- ./gradlew :micronaut-jooq:test\n- ./gradlew :micronaut-jooq:txTest\n- ./gradlew :micronaut-jooq:spotlessCheck\n\nResolves Micronaut jOOQ tries to inject mulitple possible bean(Configuration) candidates #1292

Pull request overview

Resolves Micronaut jOOQ DSLContext injection ambiguity when both JDBC and R2DBC configurations are present by separating configuration bean types and adjusting DSLContext bean creation/selection.

Changes:

• Introduce distinct internal JdbcConfiguration and R2dbcConfiguration bean types (both extend jOOQ DefaultConfiguration).
• Update JDBC/R2DBC configuration factories to return those distinct types and refactor shared configuration setup into a generic helper.
• Create separate DSLContext beans for JDBC vs R2DBC configurations and add a regression spec for the combined setup.

@Primary on an @EachBean(R2dbcConfiguration.class) factory method makes every generated R2DBC DSLContext primary. If the app has multiple ConnectionFactory/R2dbcConfiguration beans (e.g., default + others), this will produce multiple primary DSLContext beans and reintroduce injection ambiguity for unqualified DSLContext injection. Consider avoiding method-level @Primary and instead expose a single primary/alias DSLContext bean that points to the desired default (e.g., the primary R2dbcConfiguration), or apply @Primary only to the default instance via qualifier-based selection.
