fix: make interactive prompt placeholders behave like defaults or cla…

[felipefreitag]

Summary

• Add defaultValue support to shared prompt helpers (requireText, promptForMissing) and fix validation bug that rejected empty input before defaultValue could apply
• Use defaultValue in emails send so first-time users can press Enter through all prompts and send a working test email to delivered@resend.dev
• Prefix ambiguous placeholders with "e.g." across commands (broadcasts, templates, segments, topics, contact-properties, api-keys) to clarify they're examples, not defaults
• Remove misleading Jane/Smith placeholders on optional contact name fields
• Extract verified domain picker (fetchVerifiedDomains, promptForFromAddress) into shared src/lib/domains.ts and reuse in broadcasts create
• Trim from-address prefix options to noreply and hello + "Custom address..."

<violation number="1" location="src/lib/domains.ts:57">
P2: The new validation no longer enforces that the custom address uses the selected verified domain, so users can enter `foo@other.com` and only find out later when the send fails. Restore the domain check here.</violation>
