[Performance] ReportActionAvatars — report-type wrappers (parallel PRs)

[mountiny]

Parent tracking issue: #94584

Deliverables

One PR per wrapper. Each PR builds the wrapper and flips its getIcons branch in the ReportAvatar dispatcher. These can be worked in parallel after the dispatcher (step 5) lands.

• ExpenseReportAvatar (isExpenseReport) — Subscript (user + workspace); subscribes to report + policy + personalDetails
• ExpenseRequestAvatar (isExpenseRequest) — Subscript (actor + workspace); subscribes to report + parent report action + policy + personalDetails
• IOUReportAvatar (isIOUReport) — Diagonal (manager + owner); subscribes to report + personalDetails
• InvoiceReportAvatar (isInvoiceReport) — Diagonal (B2B 2 workspaces), Subscript (workspace + user); subscribes to report + policy + invoiceReceiverPolicy + personalDetails
• TaskReportAvatar (isTaskReport) — Single (owner), Subscript (owner + workspace); subscribes to report + policy + personalDetails
• GroupChatAvatar (isGroupChat) — Single (group avatar); subscribes to report only
• PolicyExpenseChatAvatar (isPolicyExpenseChat) — Subscript (workspace + user); subscribes to report + policy + personalDetails
• RoomAvatar — Single (workspace), Subscript (invoice room: workspace + receiver); domain room = report only; policy/user-created rooms need policy; invoice rooms need invoiceReceiverPolicy + personalDetails
• ChatThreadAvatar (isChatThread) — Single (actor), Subscript (actor + workspace); last fallback for thread reports; subscribes to report + parent report action + policy + personalDetails

Notes

• Blocked by ReportAvatar dispatcher (step 5)
• Once all merge, no branch uses the fallback to ReportActionAvatars

This issue has not been updated in over 15 days. @jmusial, @roryabraham eroding to Monthly issue.

P.S. Is everyone reading this sure this is really a near-term priority? Be brave: if you disagree, go ahead and close it out. If someone disagrees, they'll reopen it, and if they don't: one less thing to do!
