refactor: wire Dashboard, ListIssues, and ListPulls to use template files

Replace inline fmt.Sprintf HTML generation in Dashboard, ListIssues,
and ListPulls handlers with template.ParseFiles rendering of
dashboard.html, issues.html, and pulls.html respectively.

ListIssues now reads ?org= and ?state= query params to filter results.
ListPulls now reads ?org= query param to filter results.

Closes leeworks-agents/gitea-mobile#34
