Daily Rounds Enhancements - Part 1: Drop support for "copy previous log update" in favour of events

[rithviknishad]

Currently, Daily Rounds has a checkbox: "Copy from Previous Log Update" which copies the previous daily round record's values to the new record.

However, this makes it difficult to properly track last known value of a specific field.

Since "Events" has been introduced, each of the field groups could be updated individually.
