Backport #29069
The old code `GetTemplatesFromDefaultBranch(...) ([]*api.IssueTemplate,
map[string]error)` doesn't really follow Golang's habits, then the
second returned value might be misused. For example, the API function
`GetIssueTemplates` incorrectly checked the second returned value and
always responds 500 error.
This PR refactors GetTemplatesFromDefaultBranch to
ParseTemplatesFromDefaultBranch and clarifies its behavior, and fixes
the API endpoint bug, and adds some tests.
And by the way, add proper prefix `X-` for the header generated in
`checkDeprecatedAuthMethods`, because non-standard HTTP headers should
have `X-` prefix, and it is also consistent with the new code in
`GetIssueTemplates`
Backport #26521 by @JakobDev
Blank Issues should be enabled if they are not explicit disabled through
the `blank_issues_enabled` field of the Issue Config. The Implementation
has currently a Bug: If you create a Issue Config file with only
`contact_links` and without a `blank_issues_enabled` field,
`blank_issues_enabled` is set to false by default.
The fix is only one line, but I decided to also improve the tests to
make sure there are no other problems with the Implementation.
This is a bugfix, so it should be backported to 1.20.

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.
