refactor(note): cut JVM/Android ties out of the NoteCompose tree; translation and note slots

KMP swaps so the note types can live in commonMain:
- formatDateTime(DateTimeStyle) replaces SimpleDateFormat in NoteCompose, DisplayOts,
  CalendarEvent, Attestation, MeetingSpace and the live-stream flags
- DecimalPatternFormatter, PlatformNumberFormatter and the quartz BigDecimal (plus
  parseBigDecimalOrNull) replace java.text / java.math in the zap, goal, reward, poll,
  medical, classifieds and software-app types
- phonePrefersMiles() is a commons expect; timeDiffAgo* and formatSecondsToTime are common
- UrlInfoItem resolves OpenGraph URLs through resolveHttpUrl and moves to commonMain with
  the URL preview card, recording indicators and streaming flags
- NIP-95 local media is an okio Path from Nip95BlobStore.path(id)
- ic_dm, nip_05 and profile_banner move to commonsUI Compose resources (painterRes)
- podcast chapters/transcripts fetch through fetchPreviewText; live streams probe through
  isVideoOnline; the event "copy JSON" goes through toPrettyJson

Platform verbs as small commonsUI expect/actuals: rememberTextSharer (share sheet),
rememberShortNotice (toast), rememberBlossomUriOpener, argbPixelsToImageBitmap. Plain VIEW
intents use LocalUriHandler; the zap poll pays through AccountViewModelHost.

Slots: TranslationPlatform (Play installs ML Kit, F-Droid none) behind a shared
TranslatableRichTextViewer; RichTextPlatform gains SecretMessage; the preview
AccountViewModel mocks move to commonsUI. NotePlatform (media players, map, audio/chess/
git/meeting/napplet note types, reactions row, post editor) is defined with its Android
implementation installed in the theme; call sites are switched in the next step.

+ * reactions/zap row with its wallet hand-offs, and the post editor.
