fix: gohttpserver checksum verification fails due to wrong working directory

[Copilot]

sha256sum --check resolves filenames relative to CWD (/app), but the tarball is downloaded to /tmp/, causing a "No such file or directory" error and build failure.

Changes

• Dockerfile: Replace sha256sum --check pipe with explicit hash comparison — fetch the expected digest from the checksums file, compute the actual digest against the full /tmp/ path, and fail loudly on mismatch:

EXPECTED=$(curl -fsSL ".../gohttpserver_1.3.0_checksums.txt" \
  | grep "${TARBALL}" | awk '{print $1}') && \
ACTUAL=$(sha256sum "/tmp/${TARBALL}" | awk '{print $1}') && \
[ "$EXPECTED" = "$ACTUAL" ] || (echo "Checksum mismatch for ${TARBALL}" && exit 1)

This section details on the original issue you should resolve

<issue_title>Add gohttpserver for web-based file management</issue_title>
<issue_description>In order to manage OpenClaw effectively, access to the gateway is given, and access to ttyd (browser-based terminal access) also.

To complete ease of management we need to give users access in the same way to a file manager so they can change the files themselves. Gohttpserver seems to be an accepted solution.

</issue_description>

<agent_instructions>Add gohttpserver and expose it and then give a link in /dappnode_package.json like in here: "links": {
"homepage": "https://openclaw.ai",
"ui": "http://openclaw.dappnode:18789#token=openclaw",
"terminal": "http://openclaw.dappnode:7681",
"setup-wizard": "http://openclaw.dappnode:8080",
"docs": "https://docs.openclaw.ai"

So users can easily access the gohttpserver by clicking this link.

Implementation should be very similar to ttyd</agent_instructions>
