0.4.3

Adds a Sync now row action to the Partners screen, so you can pull a partner's listings on demand instead of waiting for the hourly sync.

• Available for every non-blocked partner, next to Block and Refresh keys.
• Ignores the failure backoff: clicking it on a partner that has been failing retries immediately, and any error is shown in full on the screen instead of only in the Activity log.
• A successful sync reports what changed: listings created, updated, and tombstoned.
• Manual syncs don't reset the scheduled-sync watchdog, so a site whose wp-cron is asleep still gets warned about it.

Partnering carries no obligation to import — this is the first step toward finer control over what you consume from each partner.
