Fix long project name display in issue list and in related dropdown (#23653)

This PR is to fix the second problem mentioned in #23625, along with the
long texts problem in `issue-item-bottom-row` of `issuelist.tmpl`

Main changes are:
1. Add `max-width` to the search dropdowns in issue list and make the
possible long texts inside to show ellipsis if texts are long
2. Adjust the conditions in
[issuelist.tmpl](https://github.com/go-gitea/gitea/blob/1d35fa0e784dffcadacb2322a3d7ac3ec2ff89b2/templates/shared/issuelist.tmpl#L146-L167)
to fix the problem as mentioned by the
[comment](https://github.com/go-gitea/gitea/issues/23625#issuecomment-1479281060)
3. Use `word-break: break-word;` in `issue-item-bottom-row` to break the
possible long texts.

dropdowns with long name (Here take reference from github to deal with
the long names cases: show ellipsis with no title, because all these
options are clickable, and it might not be necessary to add titles to
them ):
