Closes #1564.

Import no longer throws on a bad field. TeamProfileCodec.decode cast fields with as int? / as String?; a hand-edited or newer file with "port": "5432" raised a TypeError (not a TeamProfileFormatException) and the whole import failed.

• New TeamProfileCodec.read(source) returns the rows and the number of skipped entries; decode is read(...).rows, so existing callers keep working.
• An entry is skipped (and counted) when it is not an object, has no type or name, or has a field of the wrong type. It is skipped as a whole rather than imported without that field: a connection with its port or host dropped would point somewhere else. null fields are fine.
• The import toast says how many entries were unreadable and skipped.

More secret keys are scrubbed from driverOptions and from the connection-string query, on export and again on import: pwd, private_key / privateKey, access_key / accessKey, credential(s), signature, besides the existing pass*, secret, token, api_key. authSource and sslmode stay.

Tests: each new key on export and on a hand-edited import; wrong-typed fields, entries that are not objects or lack type or name, and null fields; decode still returns just the rows.
