Restructure network documentation for Ethereum L2 migration

[kingsleydon]

Summary

This PR restructures the network documentation to reflect Phala Network's migration from Parachain to Ethereum L2 with GPU-based compute providers.

Key Changes

📁 New Documentation Structure

• Overview Section (/network/overview/):

  • Added 6 new pages covering network basics, staking, governance, treasury, token transfers, and block explorers
  • Focused on the new Ethereum L2 architecture
  • Pages ordered according to the specified numbering scheme (2.1-2.6)

• Compute Providers (/network/compute-providers/):

  • New comprehensive introduction covering GPU mining, tokenomics, vPHA mechanics, and reward distribution
  • GPU deployment guides with step-by-step instructions (3.2.1)
  • On-chain registration documentation (3.2.2)

🗑️ Removed Legacy Content

• Removed 45 old files related to parachain-specific infrastructure:
  • SGX workers, PRB deployment, gatekeeper setup (8+2+7 files)
  • Old blockchain tech specs (4 files)
  • Outdated reference materials (26 files)

🔄 Redirects (129 rules updated)

All removed pages now redirect to appropriate new locations:

• 45 new redirects for deleted network documentation
• 82 fixed redirects that were pointing to non-existent pages
• 1 uncovered link redirect added
• 1 compute-providers parent redirect

Redirect destinations:

• Old compute provider pages → New GPU deployment guides or introduction
• Old reference pages → /network/index or corresponding new sections
• Old basic-guidance pages → /network/overview/get-pha-and-transfer
• Old gatekeeper pages → /network/compute-providers/introduction

📚 Legacy Documentation Preserved

Old parachain documentation remains accessible under "Legacy Parachain Documentation" group for historical reference.

Impact

• Deletions: 4,564 lines removed
• Additions: 998 lines added
• Net change: -3,566 lines (cleaner, more focused documentation)
• Files changed: 54 files
