Issue

When logging in to the website (https://exe.dev/auth), the magic link email has misleading copy:

• Email subject: "Verify your email - exe.dev" (should indicate login action)
• Email body: States that clicking the link will "verify your email address" (should say "log in")

The email copy should be updated to accurately reflect that this is a login action, not an email verification step.
