refactor(traefik): BREAKING CHANGE move traefik to new CRD's and move config to tc-system (#9116)

**Description**
Traefik couldn't be updated due to CRD namespace chagnes.
This PR changes the CRD namespace to `traefik.io` as required, so we can
actually update traefik.

Besides this, it moves the portalhook from either `default` or
`tc-*ingressclassname*`
to `tc-system` (our project config storage namespace). In case of
ingressclass use, `portalhook` will get a suffix instead

the reason behind this is, is the fact non-SCALE users currently cannot
use ingressclass at all and neither can platforms without a `default`
namespace.

This will require all apps to be updated accordingly, as the name and
location of the middleware also changes to `tc-system`, including a
suffix with the ingressClass name where needed.

This move of portalhook, also allows us to fix the "loadbalancer port
suffixed to ingress" bug on SCALE portal button.

**⚙️ Type of change**

- [ ] ⚙️ Feature/App addition
- [ ] 🪛 Bugfix
- [x] ⚠️ Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [x] 🔃 Refactor of current code

**🧪 How Has This Been Tested?**
<!--
Please describe the tests that you ran to verify your changes. Provide
instructions so we can reproduce. Please also list any relevant details
for your test configuration
-->

**📃 Notes:**
To be clear: IngressClass is still not 100% supported.
But that doesn't mean we should make it inherently problematic.

The "Breaking" portion of this PR, is just the fact all charts/apps have
to be updated accordingly or otherwise would not function with ingress
anymore. It does not require manual intervention byond updating, hoever.
