1. Remove unused fields/methods in web context. 2. Make callers call target function directly instead of the light wrapper like "IsUserRepoReaderSpecific" 3. The "issue template" code shouldn't be put in the "modules/context" package, so move them to the service package. --------- Co-authored-by: Giteabot <teabot@gitea.io>
