## Description

<!-- SECTION:DESCRIPTION:BEGIN -->

## Summary

The `/dev/oban/crons` dashboard page crashes with `Elixir.MatchError` when rendering cron job history sparklines. This happens because Oban Web's `TableComponent.sparkline/1` calls `DateTime.from_naive!/2` which expects a `NaiveDateTime` struct, but receives a raw ISO 8601 string from SQLite.

This will be resolved when oban_web ships https://github.com/oban-bg/oban_web/commit/9e9b7ad470ac87cfcad67bec9140dc318549dc09

<!-- SECTION:DESCRIPTION:END -->

## Acceptance Criteria

<!-- AC:BEGIN -->

- [ ] #1 Visiting /dev/oban/crons no longer crashes with MatchError
- [ ] #2 Cron history sparklines render correctly showing job state colors
<!-- AC:END -->
