FX.156 Tooltips: one Bootstrap engine everywhere; the other tooltip methods are gone

Tips were drawn five ways: app-tooltips.js (Bootstrap, from title), a hand-made .ws-tooltip div in the workspace, a second Bootstrap instance for cut-off text in Settings, one each for the area badge, the download copy button and CivilCraft's narrow number boxes, and a CSS ::after bubble on the status bars. Now app-tooltips.js is the only one: it reads data-ws-reason, title or an old data-bs-title, and offers ccTooltips.showText(el, text) for text a page computes (cut-off text, Copied, a clipped number). The site footer and admin footer load it too, so public pages match the apps. Popped-out ribbon, panel and dialog windows get Bootstrap and the engine through ccTooltips.attach(win), so they show the same tips. Same look everywhere (.tooltip.cc-tip).
