(used to be for meso view only

better facet-options modal dialog layout + better conditional fill values in form + spacing in titling metric + no need to hard-code dynamic attrs options in html since they were added to TW.Facets in commit c4a93fb1 + sigmaListeners needed to create forms *after* dynamic attrs first scan

(previously only the navbar-brand 'ProjectExplorer' did)

facets: rationalize varnames, update doc

server_menu.json remains at project root while associated DBs are in new files called project_conf.json in each project dir

polyvalent but esp. used for https://github.com/moma/comex2/commit/1b5c4b7

POSSIBLE: remove settings_explorerjs.js from the repo and ask the users to create it from twpresets/settings_explorerjs.devdefault.js ?

first draft to test and expand
