* fix: prevent premature webhook auto-disable and allow re-enable
Use persisted failure counters when deciding auto-disable status and restore dashboard re-enable flow so webhooks are not deactivated unexpectedly after reset.
* fix: count webhook failures per failed call
Only increment consecutive failure counters after a call exhausts retries, while keeping the 30-call auto-disable threshold and stale-state protection.
* fix(docs): correct webhook SDK package name (#363)
* test: isolate webhook unit suite from mailer deps
Mock limit service in webhook unit tests so Vitest does not resolve team-service and mailer paths requiring usesend-js during CI.
