## Dashboard Settings Collapsible Fix

Fixed a critical bug in the Signet dashboard where Settings tab collapsible section headers (Agent, Embeddings, Search, Memory, Paths, Pipeline, Trust, Auth) were unclickable, preventing users from expanding/collapsing sections and managing configuration.

### Root Cause Identified
The bug was caused by a Svelte 5 reactivity cycle in `SettingsTab.svelte`. The `$effect` was tracking a reactive `configFiles` prop while calling `st.init(configFiles)`, which mutated the store state. This created an infinite re-initialization loop that caused FormSection components to unmount/remount on every reactive update, disrupting the bits-ui Collapsible context and breaking click handlers.

### Component Chain Analysis
The collapsible sections used this hierarchy:
- FormSection.svelte (wrapper)
  - Collapsible.Root (bits-ui wrapper)
  - Collapsible.Trigger (bits-ui wrapper, renders `<button>`)
  - Collapsible.Content (bits-ui wrapper)

The bits-ui trigger rendered a `<button>` with `onclick` calling `root.toggleOpen()`, but component remounts were preventing proper context propagation.

### Solution Implemented
Wrapped the `st.init(configFiles)` call in `untrack()` within the `$effect` to break the dependency cycle. This allows the effect to initialize settings without creating a reactive dependency on the configFiles prop, preventing redundant re-initialization and component remounts.

### Verification
Tested using Playwright browser automation with daemon running to load real configuration data. Confirmed collapsible sections toggled open/closed properly and form controls responded to interaction.
