docs: M/F/Z-Chain canonical naming per LP-134

Update lux-fhe.mdx and chains/thresholdvm.mdx to clarify that the
ThresholdVM substrate powers M-Chain (MPC ceremonies for external-wallet
bridge custody) and F-Chain (FHE compute) per LP-134. Legacy T-Chain
name retained only for teleportvm (LP-6332).

The Threshold VM (T-Chain) provides Multi-Party Computation (MPC) as a service for all Lux chains. It manages threshold key generation, distributed signing, and key lifecycle operations using the LSS (Lux Secret Sharing) protocol. Any authorized chain can request cryptographic operations from the T-Chain via Warp messaging.
The Threshold VM substrate powers **M-Chain** (MPC ceremonies for bridge custody of external wallets — CGGMP21, FROST, Pulsar-general) and **F-Chain** (FHE compute + TFHE bootstrap-key generation) per **LP-134**. It manages threshold key generation, distributed signing, and key lifecycle operations using the LSS (Lux Secret Sharing) protocol. Any authorized chain can request cryptographic operations from M-Chain via Warp messaging. The legacy name "T-Chain" is retained ONLY for `teleportvm` (LP-6332). New work targets M-Chain (MPC) or F-Chain (FHE).

### Why
FHE enables computation on encrypted data without decryption. On a blockchain, this means smart contracts can process encrypted balances, votes, bids, and analytics while the underlying values remain hidden. Lux FHE is the cryptographic foundation for confidential EVM execution on Lux C-Chain and T-Chain.
