feat(loader): Connection.ResourceUrl patch for GetResourceServerURL

Adds a Harmony prefix on CustomPreference.GetResourceServerURL mirroring
the existing GetApplicationServerURL pattern, gated on a new BepInEx
config key Connection.ResourceUrl. Default mirrors prod
(https://shadowverse.akamaized.net/) so the patch is functionally a
no-op until the user opts in.

To redirect at a local SVSim.ContentServer (typically on :5149 per the
project's launchSettings), set:
    [Connection]
    ResourceUrl = http://localhost:5149/

The stock client composes manifest / asset-bundle / sound / movie URLs
as GetResourceServerURL() + "dl/Manifest/{resVer}/{lang}/{plat}/..."
(and similar for Resource/, Sound/) — the trailing slash on the
returned host is load-bearing. Sidestepping the scheme accessor
(GetCDNScheme) is intentional: we supply the full URL with scheme
ourselves, the same shape the ApplicationUrl patch returns.
