closes#3855
unlike #3854, this implementation uses a generic details html tag and a bit of tailwind magic...
---
## Maintainers Note
- previously tailwind classes of the form `[-a-zA-Z:0-9_.]` was disabled, however they were enabled since they were required for the `group-open:` classes
---
## Manual Testing
1. Visit the code search results after submitting a valid query for repo (if indexer disabled) or repo, user, explore (if indexer enabled)
2. Verify thst
1. the results are unfloded/open by default
2. the chevron points down when open and right when closed

Likely still a few useless classes left, but I think I at least don't
have missed any.

Conflict resolution: Trivial
Ref: https://codeberg.org/forgejo/forgejo/issues/2776
(cherry picked from commit f22fe4e1944d8084dec7c04f064a8e782fca94d4)
By using git's ability, end users (especially small instance users) do
not need to enable the indexer, they could also benefit from the code
searching feature.
Fix#29996

In HTML, `?key=val` already means "use the current link with new query parameters"
(cherry picked from commit 4c476fa41dc29dc24afda0925023ae3d0b9707cd)
Conflicts:
templates/repo/issue/filter_list.tmpl
templates/shared/issuelist.tmpl
trivial context conflict because the lines in Forgejo have rel=nofollow
Unify all but a few search boxes to use uniform style, uniform
translations and shared templates where possible.
Remove a few duplicated search templates, e. g. code search.
