Faster template apply, smarter email invites, and stability fixes

Improvements

Applying a template is now instant. The intermediate document group mapping screen has been removed from the template apply flow. Selecting a template and clicking Apply creates the task immediately — no extra confirmation step required.
Email invites accept any paste format. When adding team members or clients to an engagement, you can now paste addresses in any common format: space-separated, comma-separated, one per line, or directly from Outlook ("First Last <email@firm.com>"). Invalid addresses are flagged inline before the invite is sent, so you can fix them on the spot instead of hitting a generic error after the fact.
Foot/Crossfoot calculator lists operands in document order. Values in the F/CF calculator are now shown in the order they appear in the PDF — page by page, top to bottom — making it straightforward to trace each number back to its location in the source document.

"Apply Valid" / "Apply Exception" no longer fails after a tick mark is removed. Re-applying a footing result to a number that previously had its tick mark removed now succeeds as expected, instead of showing a "Failed to finalize calculation" error.
AI chat panel no longer goes blank during streaming. An issue that caused the chat panel to crash and stop rendering while a response was being generated has been fixed.
Workpaper page is stable on long-running engagements. An issue causing the workpaper page to crash on engagements with a long activity history has been resolved.
