ui(tasks+devmode): friendly task titles + restyle dev-mode strip

Two unrelated UI polish items.

1. Task notification titles. The "Config_update task completed!" toast
   was leaking the literal task-type id because the friendly-name map
   in the taskCompleted listener didn't list `config_update`,
   `update_config`, or `system_update`, and the fallback only
   capitalized the first letter. Same fallback was duplicated in
   task-actions.js's started-toast path.

   Extracted into `TasksManager.formatActionTitle(action)`:
   - Adds the missing entries (`config_update`/`update_config` → "Update
     Config", `system_update` → "Update System").
   - Smarter fallback: snake/kebab → Title Case, so an unmapped future
     type renders as e.g. "Foo Bar" instead of "Foo_bar".
   - Both the started (task-actions.js) and completed/failed/cancelled
     (tasks-manager.js) notification paths now route through it, so the
     started/done pair always reads the same.

2. Dev-mode strip styling. Earlier amber-on-amber recipe read as a
   warning state; the strip is just informational. Switched to a
   neutral glass surface (rgba(text,0.04) + rgba(text,0.12) border),
   text-primary copy, and the icon alone in var(--accent). Label is
   now centered with the close button absolute-positioned on the
   right (24px / 56px right padding so the centered text never sits
   under the X).
