fix: Fixed all the code quality issues

[Prekshith-Microsoft]

This pull request focuses on improving error handling, code clarity, and initialization patterns across several backend and frontend modules. The main enhancements include more informative exception handling and logging, explicit initialization sequences, and minor code cleanups for better maintainability.

Backend Improvements

Error handling and logging:

• Replaced broad except Exception: pass patterns with explicit error handling and debug logging in stream cleanup routines in azure_openai_response_retry.py, ensuring that close failures are logged but do not mask original errors. [1] [2] [3] [4]
• In validate_bicep_params.py, made JSON parsing failure resilient by treating malformed files as having no parameters instead of silently passing.
• In delete_blob_and_cleanup, now only suppresses ResourceNotFoundError instead of all exceptions, clarifying intent and avoiding masking real errors.
• In delete_claim_container, logs and continues on cleanup exceptions instead of silently ignoring them.

Initialization and application structure:

• Refactored application bootstrap: Application_Base now separates construction from initialization, requiring explicit bootstrap() call after construction, and updated docstrings to reflect this. [1] [2] [3] [4]

Codebase clarity and maintenance:

• Replaced ... with pass or raise NotImplementedError in function stubs for clarity in type hinting and protocol classes. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]

Frontend and test cleanups

• Removed unused imports and cleaned up code in several React components and tests for maintainability and clarity. [1] [2] [3] [4] [5] [6] [7]

These changes collectively improve the robustness, maintainability, and clarity of both backend and frontend codebases.## Purpose
