refactor: Reduce complexity of incoming PDU handling
* Ignores any events pushed without a room ID * Removes needless clones for PDU size checking * Removes incorrect ACL check in incoming handler * Fast-path handling already handled outlier events * Remove redundant same-room checks, replace with useful ones * Combine event rejection and persistence in a single function * Additional safety assertions in upgrade task * Split upgrade task into multiple subroutines for reduced cognitive complexity * Only mutate current state and forward extremities in tandem * Improve code documentation to better explain the logic flow
