Silence double-toasts in manuscript fixes + Local LLM status (#2669)

[atomantic]

Summary

Continues the double-toast sweep (Refs #2669). This batch covers the pipeline-manuscript + Local LLM leftover singles — three genuine sites where a caller's own error toast stacked on top of the auto-toasting request() helper.

• ManuscriptCommentCard.jsx — generatePipelineManuscriptFix and acceptPipelineManuscriptFix both run through useAsyncAction (which toasts its errorMessage on throw) and the auto-toasting helper. Now pass { silent: true }. generatePipelineManuscriptFix had no options param at all, so a backward-compatible trailing options = {} was threaded into the wrapper (the issue's explicitly-named leftover); acceptPipelineManuscriptFix already had one. This also makes the card's accept path consistent with the accept-all preview path, which was already silent.
• LocalLlmTab.jsx — loadStatus called getLocalLlmStatus() (toasting by default) and its .catch added toast.error('Failed to load local LLM status'). Now getLocalLlmStatus({ silent: true }).

Verified-but-left-alone false positives in this area: executeMessageAction (MessageDetail) is already silent: true in the wrapper; importGmailMbox (GmailMboxImportPanel) already spreads silent: true into options; the remaining LocalLlmTab catches either set state without toasting or rely on the single request() layer via runAction; every .catch in PipelineManuscriptEditor.jsx already passes { silent: true }.

Test plan

• Updated arg-exact assertions for the new trailing options arg in ManuscriptCommentCard.test.jsx, PipelineManuscriptEditor.test.jsx (accept assertion already-silent in ManuscriptImpactPreview.test.jsx was unchanged).
• cd client && npx vitest run on the affected suites (ManuscriptCommentCard, ManuscriptImpactPreview, PipelineManuscriptEditor, PipelineEditorialChecks.muteFilter, EditorialFindingsTriage, LocalLlmPlayground): 89 tests pass.

Remaining

This issue stays open — remaining un-swept batches (re-scan before claiming; every prior batch found the advertised list stale in both directions):

• Meatspace leftovers beyond the shipped health-forms batch (Silence double-toast custom-catch sites in MeatSpace health forms (#2669) #2755) — e.g. the noted follow-up class of unconditional success toasts after a swallowed-catch delete failure in Genome/Epigenetic.
• Any residual misc singles not yet verified.

Already shipped — do not re-sweep: settings + JIRA (#2670), messages/calendar/sharing, pipeline stages/canvas (#2714), writers-room/universe/universeBuilder/digital-twin/media pages+hooks (#2682), apps/GitHub/misc (#2721), loras/media (#2723), digital-twin leftovers (#2730), creative director (#2743), meatspace health-forms (#2755).
