front: match PathStep and SuggestedOP with pathStepId

Matching via uic/trigram/ch/etc is unreliable because:

- Two OPs can have the same trigram/ch.
- The same OP could appear multiple times at different spots in a
  path.

Moreover, we had multiple variants of the matching with slight
differences. Some of the matching logic got adjusted to account
for specific bugs, while others were left alone.

Each path step can be identified with a unique ID stored in
PathStep.id. Use that instead.
