fix: Add support for DISABLED status in SES verdict enums (#110)

[sebsto]

Motivation:

AWS SES can return "DISABLED" as a valid status value for spam, virus, DKIM, and SPF verdicts when certain checks are disabled in the SES configuration. However, the SESEvent.Receipt.Verdict.Status enum was missing this case, causing JSON decoding to fail with a DecodingError when parsing SES events containing {"status":"DISABLED"}.

This issue was reported in #110, where users encountered parsing failures when processing legitimate SES events from AWS that included disabled verdict checks.

Modifications:

Added .disabled = "DISABLED" case to the SESEvent.Receipt.Verdict.Status enum in
SES.swift
Converted the existing test to a parameterized test using Swift Testing's @Test(arguments:) syntax
Added a new test case (eventBodyDisabled) that includes a SES event with spamVerdict.status set to "DISABLED"
Updated the test assertion to verify both .pass and .disabled status values are handled correctly

Result:

SES events with verdict statuses set to "DISABLED" will now decode successfully without throwing errors. The library correctly handles all valid AWS SES verdict status values: PASS, FAIL, GRAY, PROCESSING_FAILED, and DISABLED. The parameterized test ensures both standard and disabled verdict scenarios are validated automatically.
