chore: replace support@opensecret.cloud with support@trymaple.ai in emails

[devin-ai-integration]

Summary

Updates support email references in email templates with appropriate handling per email type:

Project-level emails (sent to end-users of apps like Maple or third-party apps):

• send_password_reset_confirmation_email — replaced hardcoded email with generic "please contact our support team immediately"
• send_account_deletion_confirmation_email — replaced hardcoded email with generic "please contact our support team immediately"

These templates serve all projects (Maple + third parties), so a hardcoded support email isn't appropriate. The generic text matches the pattern used by other project-level templates (verification, password reset request, etc.) which already don't reference a specific email.

Platform-level email (for OpenSecret developer portal):

• send_platform_password_reset_confirmation_email — kept as support@opensecret.cloud (this is the OpenSecret platform, not Maple)

Maple-specific email (welcome email):

• Already correctly uses support@trymaple.ai — unchanged

Also updates pcrDev.json with new PCR values since the compiled binary changed.

Review & Testing Checklist for Human

• Verify password reset confirmation emails for Maple users say "contact our support team" (not a hardcoded email)
• Verify account deletion confirmation emails say "contact our support team"
• Verify platform password reset confirmation still shows support@opensecret.cloud

Notes

A future improvement could add a support_email field to EmailSettings so each project can configure their own support address, allowing project-level emails to include the correct support contact per-project.
