fix: add Escalate button to email ticket welcome embed

gmail-poll.js was hand-rolling its own Close+Claim-only action row.
Replaced with getTicketActionRow({ escalationTier: 0 }) — same helper
panel-created tickets use. Email and Discord tickets now show identical
buttons on creation: Close, Claim, Escalate.
