Update paperless-ngx to 3.0.5

Major app jump 2.20.15 -> 3.0.5. Chart major bump (7.1.1 -> 8.0.0):
the paperless.files.barcodes.scanner value is removed (pyzbar and
PAPERLESS_CONSUMER_BARCODE_SCANNER were removed upstream), the
paperless.ocr.mode default changes from the removed "skip" to "auto",
and the startup probe budget is raised to 600s for the one-time
Whoosh -> Tantivy index rebuild. New optional values:
paperless.ocr.archiveFileGeneration, paperless.files.deleteDuplicates,
oidc.provider.tokenAuthMethod.
