Unsubscribe Func + Rapid Recipe + OAuth Webhooks

A new unsubscribe chat func with a "legally binding" handling pattern, a Rapid Basic Bot starter recipe, accurate injectOAuth docs on sendWebhook with a Salesforce example, plus a small persistence fix in the partner-bundle import tool.

Added

• unsubscribe chat func — new doc covering the func that sends the unsubscribe confirmation and resolves the chat in one step, with the on_failure → label flow recommended for legal-binding visibility.
• Rapid Basic Bot recipe — new copy-paste starter under Bot Recipes: greet, getCustomerDetails, branch to a service menu for existing customers or newOpportunity + name collection for unknown senders, then working-hours-aware handoff.
• Rapid disableSystemEvents — new newOpportunity param, defaults to true so Rapid's new-lead system event doesn't escape the bot mid-conversation with a template send. Pass false to re-enable.
• matchExpression node-traversal example — new example for branching on which earlier node(s) the chat passed through, using exists(%state:node.X%).

Improved

• sendWebhook injectOAuth — documented the real object shape (service, header, tokenPrefix) instead of treating it as a flag, listed the supported services, and added a Salesforce example with Authorization: Bearer ….

Fixed

• Partner-bundle seed inputs — values like "שם הקליניקה" on the Optima bundle in the Templates Import tool now persist to localStorage so they survive reloads.
