Migrate scorecard filters to V2 format

This updates the scorecard filter to use the new API format. The main change is replacing the category field with a more flexible types and groups structure.

Breaking Changes

The filter.category field has been removed. Use filter.types.include instead:

# Before
filter = {
  category = "SERVICE"
  query    = "description != null"
}

# After
filter = {
  types = {
    include = ["service"]
  }
  query = "description != null"
}

What Changed

• Removed filter.category field
• Added filter.types with include and exclude lists
• Added filter.groups with include and exclude lists
• The kind field is now automatically set to "GENERIC" (not exposed to users)
• Dropped cqlVersion since it's always 2.0

The new format gives more control over which entities get evaluated by a scorecard. You can now filter by multiple types, exclude specific types, and filter by groups.

Files Changed

• API models and client code
• Resource and data source schemas
• Parser for API responses
• Tests updated to cover new filter structure
• Example files and documentation

Version bumped to 0.5.0 due to breaking changes.

Testing

I ran the acceptance tests as well as set up the provider locally and testing with the new filter format.
