feat: fix asserts on client dis/connect and convert inc call to rust

Removes the asserts when adding the uaid to the uaids hash, and issue
proper disconnect call to existing client. Ensure uaid removal removes
the right client indicated by a separate UUID per client object.

Convert IncrementStorage call to pure Rust async and remove Python
implementation.

Closes #1177
