Pull request overview

This PR implements the REST-side functionality needed for managing MIB files (upload, compile, list, delete, and read/write contents) in the features/mib-compiler/rest module, wiring in a new file service and adding DTOs and tests.

Changes:

• Implemented MibCompilerRestServiceImpl endpoints for upload/compile/list/delete/get/set text backed by a new MibCompilerFileService.
• Added REST model DTOs (CompileMibResult, MibCompilerFileInfo, MibCompilerFileText) and updated OSGi blueprint wiring.
• Added an integration-style test class and updated module dependencies.
