* perf(json-editor): improve JSON editing experience
- integrate Yace for syntax highlighting, history, indentation, auto-closing, and smart line breaks.
- add copy support, cursor location feedback, and synchronized content and line-number scrolling.
- extract JSON editor utilities and cover key interactions with unit tests.
* perf(system-settings): improve JSON configuration editing
- replace raw JSON textareas with the shared editor for highlighting, validation, copy, and formatting.
- preserve field-specific examples and make placeholders visible through the transparent editor layer.
- remove duplicate formatting controls while keeping existing form validation and save behavior.
* perf(json-editor): standardize JSON inputs across admin settings
- replace pure JSON textareas with the shared editor across system settings and channel workflows.
- preserve form focus, validation, placeholders, and visual or JSON editing modes.
- add happy-dom component coverage for form bindings, controlled updates, and formatting.
* fix(json-code-editor): address accessibility review findings
- Drop the unconditional aria-label that overrode every field's
label-derived accessible name; add an optional ariaLabel prop and
set it at call sites without an associated label
- Associate standalone Labels via htmlFor/id in channel-affinity views
- Hide the highlight mirror and line-number layers from the
accessibility tree (aria-hidden)
- Give the line-number gutter an opaque background so horizontally
scrolled code no longer slides under it
- Degrade to no scroll sync instead of destroying the editor when the
line-number layer is not found
* fix(channel): debounce inline priority updates
* fix(channel): commit spinner edits only on Enter or focus leave
Blurring the inline edit input to the +/- buttons flushed the pending
priority update immediately, bypassing the container focus-containment
check and defeating the debounce. Commit now happens via the container
blur handler or explicitly on Enter. Add unit tests for the priority
update scheduler.
* fix(channel): preserve row identity when priority updates reorder channels
* fix: prevent model create from wiping existing pricing for same name
* fix(models): keep create from wiping pricing for any existing name
Prefilling from the drawer's open-time model name only covered the
missing-models entry point. Submit deletes the pricing entries for the
name in the form, which is editable and starts empty from the toolbar
"Create model" button, so both a hand-typed existing name and a renamed
prefill still dropped the configured pricing.
Track the name whose pricing was actually read into the form and scope
the delete-then-readd to it, or to a name the user explicitly priced.
Editing still clears pricing by emptying the fields, a prefilled create
does too, and a name the form never loaded is left alone -- which also
stops an edit that renames onto an existing name from destroying that
name's pricing.
Read the prefill through one shared readPricingConfig instead of
duplicating the seven-map parse in both branches, and open the advanced
section for ratios that are configured as 0 rather than only truthy ones.
