fix: simplify operation shape

[ferhatelmas]

What kind of change does this PR introduce?

Refactor

What is the current behavior?

Operation is wrapped inside into an object with type.

What is the new behavior?

Unnecessary, make it top level.

Additional context

Helps cleaning up compilation in S3 router.

Pull request overview

This PR refactors how HTTP route “operation” metadata is represented across the codebase, simplifying it from an object wrapper ({ type: string }) to a plain top-level string. This aligns S3 router precomputation with the rest of the system and simplifies downstream consumers (logging/metrics/DB strategy selection).

Changes:

• Flattened config.operation across HTTP routes from { type: ... } to a string.
• Updated request instrumentation (logging, metrics, DB connection settings) to read/write operation as a string.
• Simplified S3 router registration by removing the precompiled { type: ... } operation object and updating tests accordingly.
