fix: skill panel auto-open, thinking scroll, nav icon alignment, Safari zoom — closes #643 #638 #636 #630 (PR #647)

Four self-contained CSS/JS fixes: skill click auto-opens workspace panel (ensureWorkspacePreviewVisible before api call), thinking card body scrolls when open (overflow-y:auto), nav tab icons properly centered (display:flex), Safari iOS zoom prevented (textarea 14px->16px). Independent review by @nesquena confirmed all four correct.

 ### Fixed
 - **Default model no longer shows as "(unavailable)" for non-OpenAI users** — changed the hardcoded fallback `DEFAULT_MODEL` from `openai/gpt-5.4-mini` to `""` (empty). When no default model is configured, the WebUI now defers to the active provider's own default instead of pre-selecting an OpenAI model that most providers don't have. Users who want a specific default can still set `HERMES_WEBUI_DEFAULT_MODEL` env var or pick a model in Preferences. (Closes #646)

+### Fixed
+- **Clicking a skill no longer silently loads content into a hidden panel** — `openSkill()` now calls `ensureWorkspacePreviewVisible()` so the workspace panel auto-opens when you click a skill in the Skills tab. (Closes #643)
+- **Long thinking/reasoning traces now scroll instead of being clipped** — the thinking card body now uses `overflow-y: auto` when open, so long traces are fully readable. (Closes #638)
+- **Sidebar nav icon hit targets are now correctly aligned** — added `display:flex; align-items:center; justify-content:center` to `.nav-tab` so clicking the icon itself (not below it) activates the tab. (Closes #636)
+- **Safari iOS input auto-zoom fixed** — bumped `textarea#msg` base font-size from 14px to 16px, which prevents Safari from zooming the viewport on input focus (Safari zooms when font-size < 16px). Visual difference is negligible. (Closes #630)
