Raise Resend sync batch size default (#659)

* chore: pass resend sync batch size

Co-authored-by: openhands <openhands@all-hands.dev>

* chore: bump openhands chart version

Co-authored-by: openhands <openhands@all-hands.dev>

* chore: bump chart version to 0.7.35 after merging main

Required by validate-chart-versions CI: the PR modifies values.yaml and
the resend-sync-cronjob template, so the chart version must be greater
than the base (main) version 0.7.34.
