fix(mobile): remove log message counter (immich-app#6865)

* fix(mobile): remove log message counter

Previously, the items in the log page were numbered starting with `#0`
and increasing from top to bottom. Being new to the app, this confused
me because I would have expected that newer messages have a higher
number than older messages.

Removing the counter completely because it doesn't add any value -
log messages are identified by their timestamp, text and other details.

* Switch timestamp and context in log overview
