Remove marketing fluff from /observability for security engineers

[mike-j-thomas]

Goal

Remove marketing fluff from /observability?purpose=security

How

Replace ASM with posture on the observability page when viewing for security engineers etc.

Context

This is marketing fluff
https://fleetdm.com/endpoint-ops?purpose=security
Also, attack surface management. I think we should change it to posture.

What should it be instead? (audience == security)
=> Noah: Vulnerability detection
Vulnerabilities
Vulnerability management?
TODO
one option could be threat hunting.
Mike: Include remediation?
TODO: Finish this: ^TODO: for PMMs R US: Replace ASM with posture on endpoint ops page when viewing for security engineers etc

[fleet-release]

Fluff fades, truth shines through,
Posture replaces the old,
Clear sky for engineers.

[fleet-release]

Clear view, no fluff,
Posture in place of ASM,
Security finds trust.
