Closes CL-11948

Action failures that were a sentence-only error banner now use toast.error, the same quiet treatment as an import failure. Starting a project from home no longer renders the inline bar between the headline and the prompt.

Persistent page-state banners stay inline: the hub not answering, setup incomplete, a catalog or list that failed to load, and an invitation that could not be read. Connect-a-provider and import-approval stay inline because they carry a next step. .banner.is-error no longer sets a destructive border, so any remaining error banner is not a red outline. profiles.tsx and profile-select.tsx were not edited.

Verified:

• bun check --no-script (exit 0, 762 files)
• bun check --no-script -p packages/client (exit 0)
• bun check --no-script -p packages/zip (exit 0)
• bun check --no-script -p apps/web (exit 0)
• bun run lint (exit 0)
• bun run format:check (exit 0)
• bun test ./apps/web/src (22 pass, 0 fail, exit 0)

Gist creation rejected the PNGs (gh gist create: binary file not supported). The shots are attached on this comment instead.

1. Home page after submitting a too-short prompt (short). The failure is a toast: "At least ten characters to start a project." There is no red inline .banner.is-error between "What do you want to build today?" and the prompt.
   

2. Import confirmation stays an inline banner (not a toast). The file was not imported; Cancel was used.
   

Taken with Playwright (chromium, headless) against this branch's Vite app on http://localhost:5190, proxied to the existing hub at 127.0.0.1:8000. Ports 8000 and 5173 were left running. Sidebar project titles were replaced with the word Project before the shot.
