Personalized Name String in E-mails

[thehabes]

Closes CenterForDigitalHumanities/TPEN-interfaces#459

Summary

• Replace the hardcoded "TPEN User" greeting in email templates with the recipient's actual display name or email local part
• Add JSDoc documentation to the sendMail() utility function
• Remove .claude/ configuration files that should not be committed

Details

All emails sent by TPEN Services used a generic "Hello TPEN User" greeting, making them look impersonal and untrustworthy. Both email paths (invitation and removal/departure) already had access to user data at the point of sending but never passed it through.

Changes:

• utilities/mailer/index.js — Added optional userName parameter to sendMail() with fallback: passed name → email local part. Added JSDoc.
• classes/Project/Project.js — Updated both sendMail() call sites:
  • sendInvite(): resolves name from the user lookup already performed via getByEmail()
  • removeMember(): resolves name from userData already fetched via getSelf()

The signature change is backwards-compatible — callers without the 4th argument continue to work with the email local part as the greeting.

Test plan

• npm run existsTests — all 66 tests pass
• npm run unitTests — all non-database tests pass (MongoDB timeouts expected without a running database)
• Verify invitation email shows recipient's display name in greeting
• Verify removal email shows recipient's display name in greeting
• Verify new user invitation falls back to email local part (e.g., "Hello jane" for jane@example.com)

This doesn't address the extra space in the message, but the name fix is good.
