[CI] Sign PowerAccent.Common.dll (new managed library from #47211)

[LegendaryBlair]

Summary

Fixes the stable signed release pipeline failure (Dart build 147621162) at the "Verify all binaries are signed and versioned" task:

Not Signed: + …\extractedMachineMsi\File\BaseApplicationsFiles_File_PowerAccent.Common.dll

Root cause

PR #47211 ("[Quick Accent] Move language data to PowerAccent.Common library, refactor") introduced the new managed library:

• src/modules/poweraccent/PowerAccent.Common/PowerAccent.Common.csproj

PowerAccent.Common.dll is referenced by both PowerAccent.Core (ships in the installer root) and PowerToys.Settings (ships in WinUI3Apps; deduplicated against root by generateAllFileComponents.ps1). The DLL is harvested into the MSI's BaseApplicationsFiles component group, but the PR did not update .pipelines/ESRPSigning_core.json, so ESRP never signs it and versionAndSignCheck.ps1 correctly fails the build.

This is the same kind of omission that PR #48050 fixed for YamlDotNet.dll introduced by #40834 — a new managed library shipping in the MSI without a matching signing config entry.

Fix

One additive line in .pipelines/ESRPSigning_core.json, placing "PowerAccent.Common.dll" inside the existing alphabetized PowerAccent block (next to PowerAccent.Core.dll).

             "PowerAccent.Core.dll",
+            "PowerAccent.Common.dll",
             "PowerToys.PowerAccent.dll",

Validation

• git diff shows exactly one additive line.
• File still parses as valid JSON (ConvertFrom-Json round-trip OK).
• Audited the full file list of PR [Quick Accent] Move language data to PowerAccent.Common library, refactor #47211: PowerAccent.Common.dll is the only new shippable assembly it added (the other new project, PowerAccent.Common.UnitTests, is a test project and is not included in the installer).
• Dedup logic in installer/PowerToysSetupVNext/generateAllFileComponents.ps1 keeps only the root copy when WinUI3Apps and root copies are byte-identical, so a single root-level entry is sufficient.

Follow-up

After merge to main, cherry-pick / merge into stable to unblock the 0.100 release pipeline. This is the third (and hopefully final) PR in the 0.100 release-pipeline unblock sequence, after #48050 (sign YamlDotNet.dll) and #48054 (remove duplicate QuickAccent_SelectedLanguage_Greek_Polytonic resource).

Okay, I have seen a few of these come by today.

Can we just do one PR that fixes all of the signing problems? Do we have a systemic problem that prevents us from finding them all?

Also, can somebody please explain why we keep getting new spellcheck violations on PRs that don't add new words? Who is merging PRs with failing spell check results?
