adsmetri analyzer pass

turned adsmetri into more of a real meta ads analysis surface instead of just a budget tool. shipped lifecycle views across campaigns, ad sets, and ads, added fulfillment break-even math and daily meta p&l, cleaned up multi-account switching, and tightened the dashboard into a denser compact layout that reads faster.

the hard part was not the charts themselves, it was getting the account scoping and snapshot behavior to stop lying. campaign, ad set, and ad refreshes were easy to confuse, timezone fallback had one leftover bangkok assumption in the ui, and the chart labels/tooltips needed a few passes because the first versions were technically correct but visually bad. it’s in a much better place now, but the analyzer is still the part that needs the most discipline because small state mistakes show up as fake insight.
