Add Advanced mode to tx explorer page

follow-up to #288 - once the Inputs/Transactions section actually shows useful stuff, add a sticky "Advanced mode" toggle that reveals the technical detail we otherwise hide by default. inspired by the Quick/Advanced toggle in @Thoralf-M's explorer: https://github.com/Thoralf-M/iotatools/blob/develop/apps/explorer/src/pages/TransactionDetail.tsx

- [ ] sticky Advanced-mode toggle (localStorage, same pattern as `DateFormatContext`)
- [ ] behind it: full effects (`dependencies`, `modifiedAtVersions`, `sharedObjects`, `gasObject`, `unwrapped`, `eventsDigest` - currently shown nowhere on the page), full gas breakdown, full signature detail, expiration, lamport version
- [ ] keep the existing per-card RAW JSON toggles (`CollapsibleCard`'s `rawData` prop) as is, just make sure any new sections use the same pattern
