feat(apple): type-safe SF Symbols via SFSafeSymbols

Replaces every stringly-typed SF Symbol name with a compile-time-checked
SFSymbol case, mirroring the L10n accessor approach. A mistyped or
OS-unavailable symbol is now a build error instead of a silently blank
glyph at runtime.

Adds the SFSafeSymbols SPM package (project.yml) and migrates all call
sites: Image(systemName:)/Label(systemImage:) -> systemSymbol, and the
five symbol-carrying view properties (AppDestination.systemSymbol,
SettingsRow.icon, AboutPoint.symbol, MethodRow.icon, PolicyOption.icon)
flipped from String to SFSymbol end to end.
