fix(rapid7-insightidr): do not send a bare UUID to /alerts/ops/rrns (v1.4.1)

The run died with HTTP 400 and eight "The provided RRN: [...] is invalid",
every one a plain UUID. Two mistakes compounded.

The alert list under an investigation is not consistent about where the RRN
sits. On the ABA alert this work was built against, `id` held the RRN. On
others it holds a bare UUID. The code read `id` first and `rrn` only as a
fallback, so it picked the UUID whenever both were present.

Worse, the failure was total rather than partial. /alerts/ops/rrns validates the
whole list and rejects the entire request when one entry is malformed, so a
single bad identifier costs every alert in that batch — and with one batch, the
whole run. An investigation feed that stops dead because one alert is shaped
differently is not an acceptable failure mode.

So: read `rrn` first, and drop anything that is not RRN-shaped before the batch
is sent, counting it as alert_ids_without_rrn in the run metadata. The
investigation still arrives, its retrievable alerts still arrive, and what could
not be fetched is a number an operator can see rather than an absence nobody
would notice.

Both commands that walk this list are fixed; the selector is shared and was
checked against the two real shapes plus the empty and null cases.

This turns a total failure into a partial one. It does NOT establish that those
eight alerts are reachable at all: if they carry no RRN anywhere, they are not
in the Alert Triage system and no field_ids or batch call will produce them.
That needs the raw shape of one, which the next run of list_investigation_alerts
on the failing investigation will show.

description: "Rapid7 InsightIDR (REST API) — investigation ingestion and full lifecycle (list/get/search/create/update/assign/set-status/bulk-close), investigation alerts and Rapid7 product alerts, custom threat indicators (add/replace), log management and LEQL log/log-set queries with downloads, and user directory search."
changelog: "1.4.0 — Add get_investigations_full: the investigation with its alerts inlined, so it stays the unit that becomes an incident. Drop-in for list_investigations (results_path data, dedup rrn). | 1.3.0 — Add search_investigation_alerts: ingest only the alerts that belong to an investigation, with their full detection content, in 1+N+1 calls. Filtering search_alerts on investigation_rrn does not work — the term is accepted and silently matches nothing. | 1.2.1 — search_alerts: report a malformed terms_json with the input named and echoed, instead of json's bare \"Expecting value: line 1 column 1\". | 1.2.0 — Add the search_alerts OCSF mapper: rule_keys_of_interest carries the host, the process, its command line, its parent and the file hashes, so an alert-based feed indexes entities where the investigation feed indexed none. Validated against a live ABA alert. | 1.1.1 — list_alert_fields: default path_depth to 1 and expose the search filter. The V2 fields endpoint refuses an unbounded walk of the tree (\"root path with path depth greater than 1 is not supported for V2 without a search filter\"), so the bare call returned HTTP 400. | 1.1.0 — Add the Alert Triage API (/idr/at): search alerts, get an alert, its evidence, its actors and its process trees, plus the tenant's alert field catalogue. These carry the detection content the investigation endpoints do not — MITRE T-codes, matched rule keys, assets and accounts, command lines. MDR-gated. | 1.0.0 — Initial release: investigation ingestion (list_investigations) with an exhaustive OCSF mapper, 18 commands across investigations, alerts, custom threats, logs/LEQL search and users. API v1/v2 selectable per instance and per command."
