0047996: make core2/pos2 CSP ready

Description

Core2 applications should support Content Security Policy (CSP) headers [1].

---
[1] https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP [^]

Steps To Reproduce

1. Configure app server to include CSP header by either:

a. setting it in Apache
or
b. setting it in Tomcat (ie. apply attached diff)

2. Run pos2 (in production mode) and ensure everything is working fine
-> check developers console to ensure no script execution was prevented

Proposed Solution

1. Remove all inline scripts (if any)
2(?) Decide whether this should mode should be used in CI. Note backoffice does not support CSP. Maybe running in report only mode [1] and ensure no reports are produced.
