🔧 fix: Remove Bedrock Config Transform introduced in #9931 (#10628)

* fix: Header and Environment Variable Handling Bug from #9931

* refactor: Remove warning log for missing tokens in extractOpenIDTokenInfo function

* feat: Enhance resolveNestedObject function for improved placeholder processing

- Added a new function `resolveNestedObject` to recursively process nested objects, replacing placeholders in string values while preserving the original structure.
- Updated `createTestUser` to use `IUser` type and modified user ID generation.
- Added comprehensive unit tests for `resolveNestedObject` to cover various scenarios, including nested structures, arrays, and custom user variables.
- Improved type handling in `processMCPEnv` to ensure correct processing of mixed numeric and placeholder values.

* refactor: Remove unnecessary manipulation of Bedrock options introduced in #9931

- Eliminated the resolveHeaders function call from the getOptions method in options.js, as it was no longer necessary for processing additional model request fields.
- This change simplifies the code and improves maintainability.
