Fix bool config defaults when using OperatorConfiguration CRD

When using OperatorConfiguration CRD, boolean fields with default value
of `true` (like `enable_database_access` and `debug_logging`) were
incorrectly defaulting to `false` when not explicitly specified.

This happened because Go initializes bool fields to `false`, and there
was no coalesce logic to apply the intended defaults.

The fix changes the CRD type fields from `bool` to `*bool` (pointer),
allowing us to distinguish between "not specified" (nil) and "explicitly
set to false". Then we use the existing `CoalesceBool` utility function
to apply the correct defaults.

Fixes #2575
