chore(deployment): clarify TDX HW requirements are per-CVM, bump disk to 1TB

[barakeinav1]

Closes #3448

[claude]

Pull request overview

Clarifies that the TDX hardware requirements listed in the external operator guide are per-CVM, since operators may run two CVMs concurrently during a launcher migration. Also bumps the documented CVM disk from 500GB to 1TB (1000GB), which the PR description notes is too small for mainnet. Doc-only change, no code touched.

Changes:

• Adds a callout that the listed figures are per-CVM and operators should size the host for ~2x.
• Appends "per CVM" to the memory, vCore, and disk bullets.
• Updates the Dstack web-interface deployment instructions to use disk = 1000 GB.

Per-file summary

File	Description
docs/running-an-mpc-node-in-tdx-external-guide.md	Adds per-CVM clarification + 2x sizing note in Hardware Requirements; bumps disk to 1TB in both the requirements list and the Dstack web-UI VM settings step.

Findings

Non-blocking (nits, follow-ups, suggestions):

• localnet/tee/scripts/rust-launcher/set-testnet-env.sh:28, localnet/tee/scripts/rust-launcher/set-localnet-env.sh:9, localnet/tee/scripts/rust-launcher/deploy-tee-cluster.sh:56, localnet/tee/scripts/rust-launcher/how-to-run-deploy-tee-cluster.md:131 — these comments still cite 500 GB disk per CVM. They're localnet/testnet sizing notes so 500GB may still be adequate there, but if the 1TB figure reflects the true per-CVM disk footprint (not just a mainnet-only floor), these should be updated to keep operator-facing guidance consistent. Out of scope for this PR if intentional — flagging so it isn't lost.

✅ Approved

Pull request overview

Updates the external TDX deployment guide to clarify that the stated compute/memory/storage requirements are per Confidential VM (CVM), and adjusts disk sizing guidance for mainnet operators who may run two CVMs concurrently during launcher migrations.

Changes:

• Clarify that resource figures are per-CVM and advise sizing the TDX host for ~2x during migrations.
• Increase the recommended CVM disk size from 500GB to ~1TB and update the VM HW settings accordingly.

addressed the production side in 589eac5: bumped DISK=500G → 1000G in the deployment/cvm-deployment/ configs (default.env, sgx/kms, deploy-launcher-guide.md) and the testnet node envs (frodo, sam). Left the localnet/test 500G/128G, since those sizes are adequate for local/CI runs.
