Dominik Schmidt 1f51bad9d1 refactor(graph): scope colon-path middleware to /drives/{driveID} ...

Addresses review feedback: a sub-router middleware can re-route after all,
as long as it rewrites chi.RouteContext().RoutePath instead of r.URL.Path.
Once chi has descended into a sub-router its routeHTTP matches against
rctx.RoutePath and ignores r.URL.Path, which is why the earlier top-level
registration was thought to be required.

Move ResolveGraphPath off the top-level mux.Use and attach it to the
/drives/{driveID} sub-routers (v1.0 + v1beta1). It now reads driveID from
chi.URLParam and matches against RoutePath (the part below the drive), so
the regexes drop the version + drive prefix entirely.

RoutePath carries the percent-encoded wire form (Graph.ServeHTTP sets
RawPath), so the captured driveID/itemID/path are PathUnescape'd exactly
once - reproducing the decoded r.URL.Path a normal handler would see,
without the previous RawPath/EscapedPath workaround. r.URL.Path is now
left untouched; only chi's internal RoutePath is rewritten.

Tests are reworked to drive requests through a chi router mirroring the
production nesting (including the Graph.ServeHTTP RawPath behavior), so
chi's sub-router middleware ordering, RoutePath encoding and param
round-trip are all covered indirectly: a chi upgrade that changes any of
them fails these tests instead of silently breaking colon-path lookups.
Adds explicit coverage for percent-decoding (%20, %252F) and the `$`/`!`
sub-delimiter id round-trip.
