fix: use mergeOverwrite to properly override ConfigMap values

Fixes an issue where boolean values from bundle files were not being
properly overridden by values-<component> ConfigMap entries.

The Helm merge function has a bug when merging boolean values where
true from the first dict doesn't get overwritten by false from the
second dict. Using mergeOverwrite ensures ConfigMap values take
precedence over bundle values as intended.

Example:
- Bundle: autoDirectNodeRoutes: true
- ConfigMap values-cilium: autoDirectNodeRoutes: false
- Before: result was true (incorrect)
- After: result is false (correct)

This fix ensures that users can properly override any component
configuration using the values-<component> pattern in the cozystack
ConfigMap.
