docs: fix broken README report links and unify malware report headings

[pulorsok]

Description

Fixes the broken View links in the README malware family table, and unifies the per-family section headings in the analysis report.

Changes

• README.md: update all 19 family View links from quark_rules.html#... to malware_report.html#... (the page that actually hosts the report content).
• docs/source/malware_report.rst: standardize the last four family headings to the New Quark Rules For <Family> format (BRATA, Cerberus, SuperCardX, NGate), and fix casing for Anubis, GodFather, TangleBot. This makes the section anchors consistent so the README links resolve correctly.

Closes #940
Closes #941

Closing this for now: the section-heading naming convention is still under discussion. A new PR will follow once the format is finalized.
