feat: lib updates and more (#1187)
This PR performs the following changes:

- update python in Dockerfile
- updates all python libraries (including Django)
- makes md5sum calculation redundant by default
- updates Postgresql used in Docker. For new installations this is ok. For existing ones this is backwards incompatible, and restore through pg_dump+pg_restore has to be performed in order to utilize Postgres 17 (since its not compatible with previous versions and will complain)
- fixes issues with HLS, and adds test to ensure they won't happen again
- allows . and @ in usernames

Configure ImageMagick policies.
Domains include system, delegate, coder, filter, path, or resource.
Rights include none, read, write, execute and all. Use | to combine them,
for example: "read | write" to permit read from, or write to, a path.
Use a glob expression as a pattern.
Suppose we do not want users to process MPEG video images:
<policy domain="delegate" rights="none" pattern="mpeg:decode" />
Here we do not want users reading images from HTTP:
<policy domain="coder" rights="none" pattern="HTTP" />
The /repository file system is restricted to read only. We use a glob
expression to match all paths that start with /repository:
<policy domain="path" rights="read" pattern="/repository/*" />
Lets prevent users from executing any image filters:
<policy domain="filter" rights="none" pattern="*" />
Any large image is cached to disk rather than memory:
<policy domain="resource" name="area" value="1GP"/>
Use the default system font unless overwridden by the application:
<policy domain="system" name="font" value="/usr/share/fonts/favorite.ttf"/>
Define arguments for the memory, map, area, width, height and disk resources
with SI prefixes (.e.g 100MB). In addition, resource policies are maximums
for each instance of ImageMagick (e.g. policy memory limit 1GB, -limit 2GB
exceeds policy maximum so memory limit is 1GB).
Rules are processed in order. Here we want to restrict ImageMagick to only
read or write a small subset of proven web-safe image types:
<policy domain="delegate" rights="none" pattern="*" />
<policy domain="filter" rights="none" pattern="*" />
<policy domain="coder" rights="none" pattern="*" />
<policy domain="coder" rights="read|write" pattern="{GIF,JPEG,PNG,WEBP}" />
