Add log level configuration support to VirtualMCPServer (#2837)

Add debug log level support to VirtualMCPServer

Adds LogLevel field to VirtualMCPServer CRD OperationalConfig to allow
enabling debug logging for vMCP instances. The field accepts only 'debug'
as a valid value. When not set, the vmcp binary defaults to info level.

When LogLevel is set to 'debug', the --debug flag is passed to the vmcp
container. The containerNeedsUpdate function now tracks container args
changes to ensure deployments are updated when debug is enabled or disabled.
This is necessary because the vmcp binary's logger initializes before the
config file is loaded, requiring the flag at startup.

Update existing test cases to include Args field checking. Add new test
cases for both log level change scenarios: enabling debug and removing
debug from the CR. Remove completed TODO for operational log level env var.

Bumps CRD chart version from 0.0.74 to 0.0.75.

Fixes #2781
