A clearer subscription timeline

A subscription's timeline — the running history of everything that's happened to a contract — is now clearer to read and more complete.

Two improvements landed:

• The initial order now appears in the timeline. The very first order that started the subscription is shown alongside the later renewals and changes, so you can trace the contract all the way back to where it began.
• Timeline text is now formatted. Entries render with proper formatting instead of flat plain text, making each event easier to scan at a glance.

Together these give you a fuller, more legible record of each subscription — useful when you're answering a customer's question about their history or checking exactly what happened on a contract and when.
