KM Koushik e3e9635a5f feat: add customizable contact double opt-in flow (#350)
* feat: add customizable contact double opt-in flow

* test: add double opt-in service coverage

* fix: address review comments for double opt-in PR

- Make pending status conditional on doubleOptInEnabled flag
- Backfill legacy unsubscribeReason for reliable pending detection
- Add doubleOptInContent to contact book listing select
- Fix duplicate toast on DOI editor subject save failure
- Harden searchParams parsing against string[] values
- Make default DOI template use link mark for clickable URL
- Make public API create+update atomic via transaction
- Prevent contact upsert failure when DOI email send fails

* fix: harden double opt-in confirmation safeguards

Preserve explicit unsubscribe intent in DOI flows and prevent confirmation links from re-subscribing opted-out contacts. Also sanitize subscribe-page error messaging and use timing-safe hash comparison for link verification.

* ui stuff

* fix: require doubleOptInUrl in double opt-in templates

* feat: add configurable from address for double opt-in emails

* feat: add resend confirmation flow for pending contacts

* fix: move subscribe confirmation to explicit POST flow

* test: add contact book public API endpoint coverage

* docs: add double opt-in documentation and update OpenAPI spec

Add a user guide for the double opt-in feature covering setup, contact
statuses, email customization, template variables, and best practices.
Update the OpenAPI spec to include doubleOptIn fields in all contactBook
request/response schemas.
