PB-1510: Update django and other packages

[msom]

Updates django to 5.2 (next LTS) and other packages to the latest version.

I also removed

• pins to minor versions since python packages typically follow semantic versioning
• most of the pins for dev packages (only keep pins for matching stubs and types)

While testing the docker image, I noticed that dockerrun does not work (and probably never has).

Fixed:

• Use the current env file (may be set using the ENV_FILE env variable, defaults to .env.local / .env)
• Remove LOGS_DIR configuration (I think this is a a copy paste thing from service-stac)
• Remove SCRIPT_NAME (there is nothing in the code that evaluates that, no clue what that supposed to do)
• Use settings_prod (settings_dev won't work)
• Set ALLOWED_HOST
• Start gunicorn, not python when running the command
