The /api/ subtree is routed on the main mux, so the browse case in the web
ServeHTTP switch was shadowed by the apiRouter catch-all and 401'd. Moved to
ServeSharingAPI behind RequireAuth+CsrfProtect, matching /api/storage/.
Found by live validation.
New top-nav category with the Halozati megosztas page: enable/server-name card,
household password, shares table (Nev/Mappa/Irasvedett/Felhomentes/Torles), and
a create flow (new folder under <storage>/shares or an existing folder via the
browse modal). Every customer path goes through sharingResolvePath: absolute ->
EvalSymlinks -> containment in a registered live storage root -> deny-listed
system subtree check -> is-a-directory. Refusals are UNIFORM so the picker is
never a filesystem oracle. Deny-list derived from ProtectedHDDPaths (provably a
subset); the drive root is an exact-match denial so user-data folders under it
stay shareable. samba infra metadata + i-share icon. Gates green.
