fix(web): open settings modal before populating it

openSettingsModal() populated every field and ran render helpers
(renderGroupVisibleList, renderAllAccounts, initAppPasswords) BEFORE the final
openModal() call, so an error in any of them left the modal unopened — the
"settings button does nothing" report. Now the modal opens first and the
populate step runs in try/catch (errors logged, not fatal). v76.
