refactor(accesslog): restructure access logging; enhance console output format

Major refactoring of the access logging infrastructure to improve code organization and add proper console/stdout logging support.

- Renamed `Writer` interface to `File` and consolidated with `SupportRotate`
- Renamed `Log(req, res)` to `LogRequest(req, res)` for clarity
- Added new `ConsoleLogger` with zerolog console writer for formatted stdout output
- Moved type definitions to new `types.go` file
- Changed buffer handling from `[]byte` returns to `*bytes.Buffer` parameters
- Renamed internal files for clarity (`access_logger.go` → `file_access_logger.go`)
- Fixed fileserver access logging timing: moved logging after handler execution with defer
- Correct response handling in Fileserver
- Remove deprecated field `buffer_size`
- Simplify and removed unnecessary code

All callers have been updated to use the new APIs.
