Move Google Analytics ID into web/config.js (optional)

[telivity-otaip]

Why

web/index.html hardcodes a Google Analytics (gtag) ID. Self-hosters should not ship Telivity’s analytics by default.

Task

1. Read the gtag block at the top of web/index.html.
2. Move the measurement ID into web/config.example.js as something like analyticsId: '' (empty = disabled).
3. Only inject/load gtag when CAREEROPS_CONFIG.analyticsId is set.
4. Document the option in web/README.md (one short paragraph).

Acceptance

• Fresh clone with empty analyticsId loads no gtag script
• Setting an ID in config.js enables analytics
• No secrets committed; config.js stays gitignored

Tips

Small, frontend-only change. Test by viewing page source / Network tab for googletagmanager.com.
