Paperless-ngx: convert glob ignore patterns, restart crashed services

v3 compiles PAPERLESS_CONSUMER_IGNORE_PATTERNS as regex, so a v2 glob
like "*.tmp" kills the consumer on start and "._*" ignores every file.
The update now rewrites such globs to anchored regex instead of only
warning.

The four units had no Restart=, so an OOM kill during a large mail
import left the webserver and task queue down. Install sets
Restart=on-failure and the update adds it to existing units.
