Closes #1898. Closes #1900.

Two issues, one omission.

With a region filter active, VCR replay on the Live map rendered
**nothing at all** (#1898), and the Replay button on packet detail
**silently did nothing** (#1900).

## Cause

`packetMatchesRegion` (`public/live.js:80-92`) matches a packet group by
looking up `packets[i].observer_id` in the observer roster map. A packet
whose `observer_id` is null is skipped, and when none match it returns
`false` and the caller drops the whole group (`live.js:3374`).

`dbPacketToLive()` returned `observer` (the resolved name) but never
`observer_id`. So every replayed packet was skipped, and every group was
dropped. The Replay button had the same gap: both branches passed
`obsName(o.observer_id)` and threw the id itself away.

**The value was there the whole time.** The VCR builds its entries with
`Object.assign({}, p, obs, ...)`, so the observation's `observer_id` is
on the input, and the server has returned `observer_id`, `observer_name`
and `observer_iata` per packet since `cmd/server/db.go:345-347`. Only
the object literal dropped it.

## Fix

Carry `observer_id`, and `observer_iata` alongside it so
`obsIataBadgeHtml` (`live.js:102-108`) can use the direct field for
replayed packets instead of falling back to the roster map.

Three lines of behaviour, in two files.

## Verification

Four regression tests in `test-live-region-filter.js`. **Three fail
without the fix**, checked by reverting `live.js` and re-running:

```
 #1898: dbPacketToLive carries observer_id through
 #1898: a replayed packet survives an active region filter
 #1898: dropping observer_id is what broke it (guards the regression)
 #1898: observer_iata is carried so the badge needs no roster lookup
```

The one that passes either way does so on purpose: it asserts a packet
carrying **no** `observer_id` is still dropped, pinning the mechanism so
a future change cannot make the filter match everything.

That test's sandbox needed `getParsedDecoded` and `getParsedPath`.
`live.js:14` captures those from `packet-helpers.js` at load time and
the sandbox does not load it, so they are stubbed in the sandbox
definition rather than assigned afterwards. Assigning later is too late
for that capture, which cost me two attempts.

Other suites unaffected: `test-live.js` 95 passed,
`test-packet-filter.js` 99, `test-frontend-helpers.js` 656.
`test-1110-live-filter.js` fails identically on unmodified master with
`ERR_CONNECTION_REFUSED`; it is an E2E test needing a server on port
13581.

## Note

Both issues were filed separately and neither names the other. They are
the same root cause in sibling code paths, which is why they are fixed
together rather than in two PRs.
