docs(readme): organized Support/Donate section (PIX, crypto, Open Collective, Ko-fi, BMC, Liberapay) + categorized top nav (#8991)

* docs(readme): add Support OmniRoute donate section (PIX live) and rename community section

- Replace bullet '❤️ Support' with a full '💚 Support OmniRoute' table (nowrap pattern):
  Star, GitHub Sponsors, Open Collective, Ko-fi, Buy Me a Coffee, Liberapay, PIX, Crypto.
- PIX: dedicated random key + static BR Code (copia-e-cola) + QR (docs/assets/pix-qr.png).
- Rename '📧 Support & Community' -> '📧 Community & Help' to drop the duplicate 'Support';
  fix the nav anchor and the 'Support the project' row to point at the new section.
- Open Collective / Ko-fi / Buy Me a Coffee / Liberapay and Crypto still marked as pending.

* docs(readme): wire up Ko-fi donation link (ko-fi.com/diegosouzapw)

* docs(readme): wire up Buy Me a Coffee donation link

* docs(readme): wire up Liberapay donation link

* docs(readme): wire up Open Collective donation link (invoice-issuing channel)

* docs(readme): reorganize top nav into one categorized table + add donate link

- Merge the two loose nav tables under '🧩 Available' into a single labeled table
  (Start / Learn / Features / See it / Support / Project), 21 links.
- Surface '💚 Support / Donate' in the nav near the top, next to Community & Sponsors.
- Drop the pre-existing broken '#-dashboard-screenshots' anchor; add '✨ What's New'.
- All 21 in-page anchors verified against github-slugger (0 broken).

* docs(readme): complete crypto donation block (BTC, ETH, USDT-TRC20, USDC-Solana)

- Fill the Crypto <details> with the four wallet addresses (coin / network / address),
  replacing XMR with USDC on Solana per owner's choice.
- Update the donate table's Crypto row to 'BTC · ETH · USDT-TRC20 · USDC-Solana'.
- Add a wrong-network warning note.

* docs(readme): label BTC network as Bitcoin (SegWit) for consistency
