* fix(sidebar): keep minimized icon rail in sync with per-tab visibility
Per-tab visibility (Customize UI / Appearance checkboxes, stored in
localStorage under `odysseus-ui-visibility`) was only applied to the full
sidebar elements — `UI_VIS_MAP` never targeted the collapsed `#icon-rail`
launchers. So a user who turned a tab off (e.g. Email) in the full view saw
every tab reappear when minimizing the sidebar to the icon rail.
Pair each tool/section selector with its `#rail-*` counterpart (mapping
mirrors `_railToolMap`), so `applyUIVis()` hides the rail launcher too.
Admin feature-flag handling is unaffected: the features-fetch reconcile at
app.js already re-applies `applyUIVis()`, so rail launchers now track admin
disables exactly like their sidebar buttons.
Adds a static regression test asserting every customizable tab pairs its
rail button.

* refactor(sidebar): extract UI visibility into testable module
Move UI_VIS_MAP, UI_VIS_DEFAULT_OFF, and a pure resolveVisibility() into
static/js/ui_visibility.js so the icon-rail visibility rules are unit
testable without a DOM. app.js applies resolveVisibility() to the document,
replacing the ad-hoc tools-section override with an inline parent rule
(tools-section off hides every tool rail launcher). Add edge-case tests
covering per-tool off, the tools-section parent rule, parent+child combos,
email-section, and the tool-library <-> #rail-archive mapping.
