Matching claim improvements

[ktprograms]

Changes made

Fix winning claim ordering logic in search

The comparison being used was $1 > $0, which caused the list to be ordered in reverse. Change to using $0 > $1.

Check if search matching claim is filtered or blocked

• Check if the claim is filtered or blocked
• Remove mature check from title/description/name as it is too restrictive (https://github.com/OdyseeTeam/odysee-ios/issues/250#issuecomment-965242920)
