Claude 22d3d8c1ff Address Codacy static-analysis findings in settings JS
Refactor the two new modules to clear the flagged patterns without any
behavior change:

- Build the search dropdown with DOM nodes + textContent instead of
  innerHTML string concatenation, removing the XSS sinks and the manual
  escapeHtml helper it needed.
- Replace numeric index access (index[i], terms[j], opts[idx],
  currentResults[i]) with array iteration methods, NodeList.item(), and
  Array.prototype.at() to clear detect-object-injection.
- Use === via a shared termsMatch() helper, optional-catch binding, and
  drop a useless initial assignment.

Verified with ESLint (eslint:recommended + eslint-plugin-security) at zero
findings and re-ran the headless-Chromium behavior test (tooltip, per-tab
filter, global search navigation) — all green.

/*
* settings-search.js — global settings search + per-tab filter for the v3 UI.
*
* Two features share one lightweight index built from the same markup the
* tooltip work standardizes (.form-group[id^="setting-"] + <label> +
* .help-tip[data-tooltip]), so it can never drift from what is rendered:
*
* 1. Global search (header box): finds settings across ALL tabs, even ones
* not yet opened, by fetching each tab's partial once and scanning it.
* Clicking a result switches to the tab, waits for the field to load,
* then scrolls to and flashes it.
* 2. Per-tab filter (the .settings-filter box under a partial title):
* hides non-matching fields on the current tab. Delegated, so it keeps
* working across HTMX swaps.
*
* No backend endpoint is required — plugins are enumerated from
* window.installedPlugins and their config partials are fetched the same way.
