Fix encryption enable by removing broken org UI references, bump to 0.9.44

Removed Organization section JS (initOrgUI, showOrgJoined, showOrgNotJoined,
setOrgStatus) and OrgPolicy import from options.js. These referenced DOM
elements deleted in a prior commit, causing DOMContentLoaded init to fail
before the encryption button listener could be registered.
