build(deps): bump oban from 2.19.2 to 2.19.4

[dependabot]

Bumps oban from 2.19.2 to 2.19.4.

Changelog

Sourced from oban's changelog.

v2.19.4 — 2025-03-25

Bug Fixes

• [Validation] Partially revert removal of unused validators.

  Some validations are actively used by the current version of Oban Pro and shouldn't have been removed.

• [Plugins] Handle and log all unexpected messages.

  Some genservers handled unexpected messages while others did not. Now all plugins and other genservers consistently handle those messages. Public facing modules, such as plugins, all log a warning about the message while internal modules ignore them.

v2.19.3 — 2025-03-24

Bug Fixes

• [Install] Use configure_new for idempotent installation.

  Prevent overwriting existing :oban configuration when running installer.

• [Sonar] Correct stale node logic for sonar tracking.

  The original code had a logical error. By calculating stale as current time + interval * multiplier, it would reject nodes that were recorded in the future relative to the current time (which is unlikely to be the intended behavior) The new code correctly identifies stale nodes by checking if they're older than the threshold.

Enhancements

• [Worker] Check for worker functions rather than behaviour

  Behaviours can't contain overlapping callbacks. In order to have a worker-like module that defines it's own timeout/1 or backoff/1, we must use an alternate callback.

• [Worker] Improve warning message on incorrect return from perform/1.

• [Telemetry] Skip logging peer events unless node leadership changes.

  The default logger only outputs peer events when something changed: either the peer became leader or lost the leader.

• [Validation] Add schema validator for tuple options.

  Being able to validate tuples eliminates the need for custom validator functions in several locations.

• [Oban] Compatiblity updates for changes in the upcoming Elixir v1.19
