fix: resolve build errors in v2 API and wiki service

- Fix wiki_index.go: use WebPathToGitPath/GitPathToWebPath instead of undefined functions
- Fix wiki_index.go: use gitrepo.OpenRepository pattern instead of repo.WikiPath()
- Fix wiki.go: use markdown.Render instead of undefined RenderWiki
- Fix wiki.go: use charset.ToUTF8WithFallbackReader instead of undefined ToUTF8Reader
- Fix wiki.go: use gitrepo.CommitsCount instead of undefined wikiRepo.CommitsCount
- Fix wiki.go: handle WebPathToUserTitle returning two values
- Fix gofmt formatting issues in v2 API files
