[BUG] divisionerror & assignments.html stacktrace on new installs with no hosts/schedules defined

[sadsfae]

On fresh quads-dev-2.1.0-20240926.noarch with no hosts created there is an initial stacktrack of quads-web:

I can get past this by creating a test host and cloud:

quads --define-cloud --cloud cloud01
quads --define-host --host testhost01 --host-type general --model R630 --default-cloud cloud01

Then I hit another issue in that wiki/assignments.html is not being rendered.

version quads-dev-2.1.0-20240926.noarch

Solution for first stack trace

• Let's render a "No hosts defined" string in the rendered /assignments page if no hosts are defined

For the second issue something else is keeping wiki/assignments.html from being rendered.

For curiosity I created a fake future cloud and schedule but we're just not rendering / finding that file.

root@host-03:~# quads --define-cloud --cloud cloud02 --description "testiiing" --cloud-owner wfoster --cloud-ticket 12345
Assignment created.
root@host-03:~# quads --add-schedule --schedule-start "2025-09-22 22:00" --schedule-end "2025-09-25 22:00" --schedule-cloud cloud02 --schedule-cloud cloud02 --host testhost01
Schedule created

On a fresh quads-dev-2.1 install on a new host the RPM isn't dropping our wiki/templates into %python3_sitelib

root@host-03:~# rpm -ql quads-dev | grep .html
/usr/lib/python3.12/site-packages/quads/web/templates/_formhelpers.html
/usr/lib/python3.12/site-packages/quads/web/templates/base.html
/usr/lib/python3.12/site-packages/quads/web/templates/dropdown.html
/usr/lib/python3.12/site-packages/quads/web/templates/links.html
/usr/lib/python3.12/site-packages/quads/web/templates/modal_no_footer.html
/usr/lib/python3.12/site-packages/quads/web/templates/navbar.html

I would also expect to see these files too unless they should be dynamically generated.

[root@quads2-stage wiki]# pwd
/usr/lib/python3.12/site-packages/quads/web/templates/wiki

[root@quads2-stage wiki]# ls
assignments.html  available.html  inventory.html  vlans.html
