Description

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

Acceptance Criteria

• #1 Visiting /dev/oban/crons no longer crashes with MatchError
• #2 Cron history sparklines render correctly showing job state colors
