Prakhar Pratyush c4330be2b1 user_topics: Validate 'topic' parameter length <= max_topic_length. ...

Earlier, 'topic' parameter length for
'/users/me/subscriptions/muted_topics' and '/user_topics' endpoints
were not validated before DB operations which resulted in exception:
'DataError: value too long for type character varying(60)'.

This commit adds validation for the topic name length to be
capped at 'max_topic_length' characters.

The doc is updated to suggest clients that the topic name should
have a maximum length of 'max_topic_length'.

Fixes #27796.
