Add settings tooltips and search to the web UI
Help users quickly find settings and understand how each one works. Tooltips: a new delegated controller (static/v3/js/tooltips.js) drives an accessible (i) info tooltip that appears on hover, keyboard focus, and tap. A shared `help_tip` Jinja macro (partials/_macros.html) emits the trigger; the plugin config macro and the core settings partials now surface help text through it. Per the design, the always-visible field help paragraphs are folded into the tooltip to declutter the forms, and the hardware/display settings carry authored detail (default, range, recommendation). Search: a global header search box finds settings across every settings tab — even ones not yet opened — via a lazy client-side index built by scanning the same field markup (static/v3/js/settings-search.js). Selecting a result switches tabs, waits for the field to load, then scrolls to and flashes it. A per-tab filter box hides non-matching fields on the current tab. Plugin settings get tooltips for free by reusing each field's schema `description`; every settings field also gets a stable `setting-<tab>-<key>` anchor id for search navigation. Styling uses the existing --color-* theme vars so light/dark mode both work, and honors prefers-reduced-motion. Adds Flask render smoke tests that assert each settings partial ships tooltips, anchors, and a filter box.

/*
|
||||
* 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.

* A single controller handles every `.help-tip` trigger on the page, including

* ones inside partials that HTMX swaps in later, with zero per-field wiring.
|
||||
* Triggers are emitted by the `help_tip` Jinja macro (partials/_macros.html) as

* <button class="help-tip" data-tooltip="..."><i class="fas fa-circle-info">.
|
||||
*
|
||||
* Behaviour:
|
||||
* - hover (mouse) -> show / hide
|
||||
* - keyboard focus -> show / hide (only for :focus-visible)
|
||||
* - click / tap -> toggle (the touch path)
|
||||
* - Escape / outside click -> hide
|
||||
* The tooltip text is set via textContent (XSS-safe) and supports "\n" line
