fix(http-client): find the generated request scratch on Windows (#356)

Generate Request in HTTP Client (and Generate Requests for Controller, and the gutter icon) left the scratch file empty on Windows with "Cannot open file …\ai.l0ng.openidea/scratches/generated-requests.http": the scratch path joined the native app data directory (backslashes) with a /-separated suffix, so the opened editor could not be found by its path. Scratch paths now normalise the app data directory to the UI's /-separated form through a shared ipcPath helper, used by scratches, the HTTP client and Spring request generation.
