feat(cli): pretty-print event JSON in the local store

Users actually look at <data-dir>/events-store/ files (cat / jq / git
diff), so the CLI now writes them with the InliningTagArrayPrettyPrinter
that quartz already had configured but never invoked. Each event is
indented with 2 spaces, but every tag array stays on a single line —
nice trade-off between human-readable and not-too-tall:

    {
      "id": "...",
      "pubkey": "...",
      "created_at": 1700000000,
      "kind": 1,
      "tags": [
        ["t","nostr"],
        ["e","abc...a"],
        ["alt","quick brown fox"]
      ],
      "content": "hi there",
      "sig": "..."
    }

Stored bytes are not the canonical NIP-01 form — but verification
re-canonicalises via EventHasher anyway, so format is purely a UX
choice. Compact stays the default for any caller that doesn't opt
in (Android keeps SQLite, generic FsEventStore embedders keep
compact).

- JacksonMapper.toJsonPretty(event): new entry point that uses
  writerWithDefaultPrettyPrinter() with the existing inlining printer.
- FsEventStore now takes an `eventToJson: (Event) -> String` callback,
  default = Event::toJson (compact). Used in insert.
- Context wires in JacksonMapper::toJsonPretty.

2 new tests in FsEventToJsonTest pin both formats (compact stays
single-line; pretty round-trips). 117 fs tests green.
