Remove dependencies superseded by native browser APIs

[Copilot]

Three runtime dependencies are replaceable with modern browser-native APIs, and husky was incorrectly placed in dependencies instead of devDependencies.

Removed packages

• file-saver — replaced with URL.createObjectURL + programmatic <a download> click (redux/actions.js)
• he — replaced with DOMParser for HTML entity decoding (components/Admin/Log.js). Uses a null-byte placeholder to preserve <br> separators before parsing so line-splitting continues to work:

  const BR_PLACEHOLDER = '\u0000BR\u0000';
  const escaped = line.replace(/<br>/gi, BR_PLACEHOLDER);
  const doc = new DOMParser().parseFromString(escaped, 'text/html');
  const lines = doc.documentElement.textContent.split(BR_PLACEHOLDER);

• redux-devtools-extension (archived/deprecated) — replaced with an inline check against the extension's global (redux/store.js):

  const composeEnhancers =
    (typeof window !== 'undefined' && window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__) || compose;

Dependency classification fix

• husky moved from dependencies → devDependencies (git hooks tool, dev-only)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cdn.ampproject.org
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node lib/warmup.js /home/REDACTED/.cache/node-gyp/24.14.0/deps/uv/include -I /home/REDACTED/.cache/node-gyp/24.14.0/deps/zlib -I /home/REDACTED/.cache/node-gyp/24.14.0/deps/v8/include -I ../../node-addon-api -I /home/REDACTED/work/synbiohub3/synbiohub3/frontend/node_modules/sharp/vendor/8.10.0/include -I (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
