Fixes and improvements

asset_url will always render a full path to file hosted in CDN, even if it does not exist in the manifest

static_cache expire config in Page will cache Page for given time
match filter error handling for invalid expression
presign url - fix for path with spaces and other special characters
deprecated current_user will return the same hash as recommended context.current_user to avoid unexpected errors
asset_url will correctly decode the name before looking it up in the manifest
removed legacy routes to correctly display 404 if the Page does not exist (internal error was returned instead for some edge cases like /webhooks)
