fix(tasks): remove non-functional reminder write params (v1.1.2)

Exhaustive FW_DEBUG investigation on both Free and Premium accounts
confirmed that taskupdate2 silently ignores all reminder fields regardless
of encoding (flat, JSON-string, PHP-bracket, all variants). Alternative
endpoints (tasksetalert etc.) are unregistered. Root cause: mobile app
Service Worker transforms reminder requests in ways not reproducible via
direct API calls. Reminders remain read-only. Recurrency write confirmed
working (flat encoding). Docs updated with full investigation findings.
