Adds the settings entry as a new Vite multi-page input. Lays down the
shared page chrome (sidebar, save bar, restart, security alert) and the
AllSetting fetch/dirty-poll lifecycle so 5d-ii through 5d-vi can drop
in tab partials without re-implementing it.
- settings.html + src/settings.js: third Vite entry; mounts SettingsPage.
- SettingsPage.vue: page chrome with the legacy two-button save/restart
bar, conf-alerts banner, and 5 a-tabs (4 always-visible + the formats
tab gated on subJsonEnable || subClashEnable). Each tab body is an
a-empty placeholder until 5d-ii…vi fill them in.
- useAllSetting.js composable: POST /panel/setting/all on mount, mirrors
the legacy 1s busy-loop dirty check via setInterval, and exposes
fetchAll/saveAll. saveDisabled flips off as soon as the user diverges
from the server snapshot.
- restartPanel rebuilds the URL (host/port/scheme/base path) from the
saved settings so users land on the new endpoint after a port or
cert change.
- models/setting.js: adopts the @/utils alias and a leading file-level
doc — semantics unchanged.
