[DerJanniku]

Requesting changes for now: this is a major backend dependency shift (sqlx 0.7 -> 0.8) without backend CI coverage in this repo. Please add backend compile/integration verification (or attach successful manual test evidence) before merging.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
