fix: serialize array field

[adrianviquez]

Adjust how we're serializing arrayfields with the sql_generator

Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. In 2022 this entity acquired Codecov and as result Sentry is going to need some rights from me in order to utilize my contributions in this PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.

Note

Improves SQL export serialization to correctly handle Django ArrayFields.

• serialize_value now accepts field and serializes lists as PostgreSQL arrays when the field is an ArrayField; otherwise lists/dicts are serialized as jsonb
• New _serialize_pg_array builds typed PG array literals with proper escaping and casts (e.g., ::integer[], ::text[])
• Enum serialization forwards field context; get_row_values passes model fields to serialize_value

Nested ArrayField produces invalid PostgreSQL array syntax

Medium Severity

The _serialize_pg_array function doesn't handle nested arrays (Django's ArrayField(ArrayField(...)) pattern). When an array element is itself a list, it falls through to the else branch and produces Python list syntax [1, 2, 3] instead of PostgreSQL array syntax {1, 2, 3}. This generates completely invalid SQL that would fail on import. Nested/multidimensional arrays require recursive serialization to produce the correct PostgreSQL format like '{{1,2},{3,4}}'::integer[][].

This is okay, we don't have nested ArrayField(ArrayField(...)) in the codebase
