Log file naming doesn't make sense

[corbin-chris]

Although logs have started having date-suffixes, these are named after the date of the previous run, instead of the datetime of the logged-run. E.g. 1st Aug writes to 2024-07-15 logs, and a run on the 18th July wrote to 2024-07-15 logs. This makes trouble-shooting more difficult.

• Change this behaviour
• Ensure Python logger deletes logs that are sufficiently old (3 or 6 months?)
• Review how logs function generally for this code
