4389447148 fix: always explicitly start a new transaction 
Active read only transaction can be aborted by doing a commit and then
issuing queries. This prevents such edge cases.

5e86e1f192 feat: db.begin(read_only=True) 
You can now start read only transaction by passing read only flag. Read
only transactions prevent any query that is of "WRITE" type like
insert/delete/update.

1dbc0b4d3c fix(db*): Use common fallback Datetime str 
There existed inconsistencies between db_query & db's fallback for min
datetime in str format - missing decimal seconds places. Now, we're
storing the default string once and re-using it to reduce
inconsistencies or room for human errors.

bc3780560e perf: Use lazy mogrified query for logging 
For parameterized queries, there's an improvement of ~30% in query
execution via frappe.db.sql - from 58.6 µs ± 2.37 µs to 44.6 µs ± 1.56 µs

effa942f4c refactor: frappe.db.log_query 
* Mogrify queries and set them as frappe.db.last_query instead of
  directly interfacing with the clients
* This is required for now as the MariaDB client uses binary protocol to
  talk to the server and doesn't build the queries itself
* Add typing hints
* Imported Query object as FilterEngine - Query is too ambiguous lol

* Include values mogrifying & executing via client alone in execution
  time for query
* Reduce indentations lol
