Simplified filing review + bulk specimen downloads

We've combined the filing review experience into a single drawer and added a few quality-of-life improvements to the filing flow. See details below!

The two review buttons (Client Summary and Review) are now a single Review + File button. Everything you need for all filing types - filing details, client email, comparison view, and export options - lives in one drawer, organized by tabs.

You can now download all specimens at once or just the ones you've attached. No more downloading them one by one (although you can still download each specimen on its own). Look for "Download All Specimens" and "Download Attached Specimens" in the export menu.

For new applications and ID conversions, the primary action is now "Open in Trademark Center" - taking you straight to where you need to go when you're ready to file.
