test: adds testing

[n3rdc4ptn]

This pull request introduces several enhancements and fixes across the codebase, focusing on task management, API updates, logging improvements, and test coverage. The most significant changes include the addition of new tasks in Taskfile.yaml, updates to the MCP usage structure, and improvements to logging and test infrastructure.

Task Management and Configuration Updates:

• Added new tasks in Taskfile.yaml for generating code and fetching external APIs, including a download-crds task to fetch CRD files from external repositories (Taskfile.yaml) [1] [2].

MCP Usage and API Changes:

• Updated MCPUsageSpec to make the daily_usage field optional by adding the omitempty tag (api/usage/v1/mcpusage_types.go).
• Removed daily_usage from the required fields in the CRD manifest (api/crds/manifests/usage.openmcp.cloud_mcpusages.yaml).

Logging Improvements:

• Replaced the custom logging utility with logr for consistency and better integration with the controller-runtime library (internal/controller/managedcontrolplane_controller.go) [1] [2] [3].

Test Enhancements:

• Added comprehensive unit tests for the ChargingTarget resolver and MCP usage reconciliation logic (internal/helper/chargingtarget_test.go, internal/controller/managedcontrolplane_controller_test.go) [1] [2].
• Introduced a new test suite for helper functions with improved test environment setup (internal/helper/suite_test.go).

Dependency and Code Cleanup:

• Added github.com/go-logr/logr as a direct dependency in go.mod and removed its indirect reference for clarity (go.mod) [1] [2].
• Simplified error handling in the MergeDailyUsages function by removing redundant comments (internal/usage/helper.go).

• The logr.FromContext function does not return an error. It should be called as log := logr.FromContext(ctx) without error handling.
