Describe the bug
When trying to setup one uptime behind Haproxy as reverse proxy, register form is trying to request with http scheme resulting in mixed content error

To Reproduce
Steps to reproduce the behavior:

Deploy oneuptime
Configure config.env to use https
Install and configure haproxy to use https and connect to oneuptime:80 without ssl
Tell haproxy to pass "X-Forwarded-Proto" header with "https" value
Register form is returning error
Mixed Content: The page at 'https://uptime.example.com/accounts/register' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://uptime.example.com/identity/signup'. This request has been blocked; the content must be served over HTTPS.

Also when trying to route request to https port, ssl error
curl -Ik -H "Host: uptime.example.com" https://localhost curl: (35) OpenSSL/3.0.11: error:0A000438:SSL routines::tlsv1 alert internal error
is raised with
ingress-1 | 2024-02-20T10:30:51.855424570Z 2024/02/20 10:30:51 [error] 22#22: *66 cannot load certificate "/etc/nginx/certs/StatusPageCerts/localhost.crt": BIO_new_file() failed (SSL: error:80000002:system library::No such file or directory:calling fopen(/etc/nginx/certs/StatusPageCerts/localhost.crt, r) error:10000080:BIO routines::no such file) while SSL handshaking, client: 172.18.0.1, server: 0.0.0.0:443
this in Ingress container log

Expected behavior
