Expand native Mod Settings with live controls and save feedback

[Guffawaffle]

Adds live controls under Settings → Mod Settings: Camera, Previews & Cargo, Map & Travel, and Fleet Labels. They share existing configuration and hotkey owners, show current values and report asynchronous save failures. Collapsible fleet sections start closed; conditional cargo rows retain preferences while hidden. FC and Forbidden Tech stay on the native confirmation page.

Depends on refreshed #281 and its #277/#280 prerequisites. Following #313, native settings and persistence use independent default-enabled [patches].nativesettingshooks and runtimeconfighooks. Forbidden Tech uses forbiddentechconfirmhooks; fleet labels install under zoomhooks, independent of feature values or UI activity. Installed callbacks read current feature values; unsupported or incomplete families retain native behavior.

Validation: Windows release build and existing settings/persistence fixtures on the compiled source, unchanged by final documentation corrections; all 11 example TOMLs. Windows client 270 static fit covers the core, navigation/widget, quit/update and fleet-label targets. Earlier combined Mac ARM testing is separate from this candidate. Exact native game smoke, Mac native extent/execution qualification and Windows partial-replacement fault injection remain outstanding.

Hook/feature alignment follow-up for #313

Follow-up to #313: keep hook installation independent of feature enablement, with default-enabled compatibility switches under [patches] and feature checks inside the installed hooks.

Use an independent native-settings installation switch rather than hardcoded installNativeSettings = true. Remove install_forbidden_tech = auto_confirm_ft_upgrade | installNativeSettings; use upstream's [patches].forbiddentechconfirmhooks, with [ui].auto_confirm_ft_upgrade checked inside the hook. Fleet-label hook installation currently depends on FleetLabelProfilesEnabled() or the settings installer; install supported hooks independently and consult [graphics].zoom_label_player_* / zoom_label_non_player_* during behavior. Preserve partial-install guards and native restoration. This is the parent of the sibling features #285, #293 and #297; propagate the corrected foundation into all three.

Settings cascade (verified from current branch ancestry): #279 → #280; #277 + #280 → #281 → #282; sibling branches from #282 are #285, #293 and #297. #285 additionally depends on #269; #297 additionally depends on #296. Correct the owning parent first, then carry the fix through every dependent branch while preserving each sibling's scope.

Implemented in 8fde63fc2d521d951d1f5c42082f3e118ed45b75. Corrected #281 is merged. Native settings and persistence use independent all-build nativesettingshooks/runtimeconfighooks switches. Forbidden Tech uses its existing compatibility switch; supported fleet-label callbacks install under ZoomHooks independent of feature/UI values. Runtime feature checks and partial-install guards remain intact. Current contract docs replace obsolete debug/platform/layout claims. Windows build and fixtures passed on unchanged compiled source; CI is queued. Native game/Mac qualification remains open. Next: propagate through HUD and settings siblings.
