openbao: fix bootstrap so it completes on 2.6.x
bootstrap.sh could not run to completion on OpenBao 2.6.1:

- Release asset names were wrong. `bao_<ver>_linux_amd64.tar.gz` and
  `bao_<ver>_SHA256SUMS` both 404; the assets are `openbao_<ver>_...` and
  `checksums.txt`. The tarball is now saved under its real name and the checksum
  grep anchored to end-of-line, because checksums.txt also lists a .sbom.json and
  `sha256sum -c` resolves each line by the filename inside it.
- `openssl rand -base64 32` appends a newline and the static seal reads the key
  file raw, so the service failed with `Error configuring seal "static": unknown
  encoding for AES-256 key`.
- The audit stanza relied on the block label being the device type. 2.6.1 requires
  explicit `type` and `path` with device settings under `options`. Worth noting the
  intermediate state: with type and path but a bare `file_path`, the server starts
  and silently ignores the log location, which is the worse failure given a wedged
  audit device stops OpenBao answering at all.
- `disable_mlock` is unsupported in 2.6.1 and warned on every start.
- Nothing opened port 8200 and ufw defaults to deny(incoming), so vps1 could not
  reach the vault. dev renders on vps1, so this would have surfaced as a timeout
  during cutover rather than here.

bootstrap-policies.sh installed beta's credentials as `deploy:deploy`, but vps2 has
no `deploy` user and both environments deploy as `agent` (env-topology.sh sets
TG_SSH_TARGET=agent@ for both; deploy.yml uses one VPS2_SSH_USER). install_creds
also printed a success line after a failed chown: the call site wrapped it in
`|| echo`, which suppresses `set -e` for everything inside the function, so it fell
through to chmod and reported an ownership it never applied. It now removes the
half-written file and returns non-zero.

Corrects the isolation rationale accordingly — separate credentials buy audit
attribution and a policy boundary against mistakes, not deploy-user isolation.

Documents the 2.6.0 root-token change (HCSEC-2026-08): `generate-root` now targets
an authenticated endpoint, so recovery keys cannot mint a replacement token and
revoking the last root token before a second admin identity exists is a one-way
door. Also corrects the runbook's `verify-parity.sh --all`, which cannot work from
a single host given the AppRole CIDR bindings.
