fix(parser)!: throw ParsingException for a value that does not convert

[pdevito3]

Summary

A filter value that does not convert to the type of its property now always throws ParsingException. Before this change, some bad values escaped the QueryKitException hierarchy. A consumer that catches only QueryKitException returned a 500 for them.

• ParseFilter catches FormatException and OverflowException and throws ParsingException.

• An enum list value such as BirthMonth ^^ ["Bogus"] or BirthMonth ^^ [Bogus] leaked a raw ArgumentException from Enum.Parse. It now throws ParsingException.

• Every conversion site (scalar, list, enum, Guid, DateTime, DateTimeOffset, DateOnly, TimeOnly) uses one path.

• The message names the value, the target type, and the property name as the client wrote it (the query name, not the member path):

  The value 'Bogus' is not a valid BirthMonthEnum for the filter property 'BirthMonth'.

• The culture number fallback (for example Rating > 4.4 in de-DE) keeps this message. Before, it replaced the message with the generic parsing message.

• The original exception stays on InnerException.

Migration

• If you catch FormatException, OverflowException, or ArgumentException from ApplyQueryKitFilter, catch ParsingException (or QueryKitException) instead.
• If you match on the old message for an invalid enum value ("There was a parsing failure..."), match on the new message.

Evidence

The verify-querykit harness ran on the memory and Postgres targets. The model has Visibility (enum) and Rating (int).

Filter	Before	After
Visibility ^^ ["Bogus"]	System.ArgumentException "Requested value 'Bogus' was not found." (exit 1)	ParsingException "The value 'Bogus' is not a valid Visibility for the filter property 'Visibility'." (exit 2)
Visibility ^^ [Bogus]	System.ArgumentException (exit 1)	ParsingException, same message (exit 2)
Visibility ^^ [Public, Bogus]	System.ArgumentException (exit 1)	ParsingException, same message (exit 2)
Visibility == "Bogus"	ParsingException with the generic message	ParsingException that names the value
Rating == "abc"	ParsingException with the generic message	"The value 'abc' is not a valid Int32 for the filter property 'Rating'."
Visibility ^^ ["Private"]	2 rows	2 rows (no change)

Tests:

• New unit tests cover the message for enum, Int32, Decimal, Guid, DateTime, Boolean, and list values. One test covers a query name alias (month). One test covers the comma culture fallback.
• New integration cases cover the enum list form on Postgres.
• Unit: 600 passed. Integration: 365 passed. dotnet build -warnaserror: 0 warnings.
• The verify-querykit feature map no longer lists Rating > "abc" and Title @= null as escapes from QueryKitException.

Merge Danger

• Breaking: the exception type changes for some bad values, and the message text changes for all bad values. See Migration.
• The message contains the client value. A server that returns the message to the client echoes the client input. It does not contain internal type paths beyond the short type name.
