1Password: Expose CreatedAt and UpdatedAt timestamps as DateTime on VaultItem

[Copilot]

• Add CreatedAt and UpdatedAt properties to Response.VaultItem class (internal model) as strings
• Expose CreatedAt and UpdatedAt properties in public VaultItem class as non-nullable DateTime
• Move parsing logic from JSON model to VaultItem.ParseDateTime method
• Remove SafeDateTimeConverter - JSON model now simple string mapping
• Properties return default(DateTime) for invalid/missing dates instead of null
• Add backing fields (_createdAt, _updatedAt) to cache parsed dates
• Add tests for parsing CreatedAt and UpdatedAt from JSON (as strings)
• Add tests for VaultItem.ParseDateTime method (valid, null, empty, invalid)
• Add tests for accessing CreatedAt and UpdatedAt on VaultItem (as DateTime)
• Update version to 28.2.0 in PasswordManagerAccess.csproj
• Update CHANGELOG.md with the new feature
• Run all tests to ensure everything works (1815 tests pass)

Summary

Optimized date handling with lazy initialization:

• Added _createdAt and _updatedAt backing fields
• Dates are parsed once on first access and then cached
• Uses null-coalescing assignment operator (??=) for lazy initialization
• Consistent with other cached properties like _fields, _overview, _details
• All tests pass

<issue_title>1Password: Created and Updated Dates</issue_title>
<issue_description>Hi there

I notice on the response data for a vault in 1Password included createdAt and updatedAt dates. These can easily be added to the data returned in the vault object. I need these dates for a project I am working on.

</issue_description>

<agent_instructions>make sure the tests are updated for this one. make sure to test the failures as well. this version should be bumped to one minor: x.y.z -> x.y+1.0. update the changelog and the csproj. don't merge the pr, let me review.</agent_instructions>

The dates should be parsed and returned as a standard datetime object in.NET. It shouldn't be strings. make sure to verify and don't throw if the dates don't parse just in case they are garbage.

Updated in commit d39fde7. The properties now return DateTime? instead of strings. Implemented a SafeDateTimeConverter that parses dates from ISO 8601 format and returns null for invalid or missing dates without throwing exceptions. All 1811 tests pass including a new test for invalid date handling.

Implemented in commit d39fde7. The CreatedAt and UpdatedAt properties now return DateTime? with safe parsing that doesn't throw on invalid input.

@copilot Make the DateTime properties non-nullable and rather use the default value. also move out the parsing from the model and JSON properties into the vault parsing code. make VaultItem.CreatedAt and UpdatedAt strings and parse later. json model should be as simple as possible and match the incoming format closely.

Updated in commit a704ffc. The implementation now:

• Response.VaultItem has CreatedAt/UpdatedAt as simple strings (matching JSON format)
• Public VaultItem properties are non-nullable DateTime
• Parsing logic moved to VaultItem.ParseDateTime() method
• Invalid/missing dates return default(DateTime) instead of null
• SafeDateTimeConverter removed - JSON model kept simple

@copilot add a backing field here and don't re-parse the date every time. make sure it is parsed once and then cached.

[Copilot]

Added in commit d573747. The properties now use backing fields _createdAt and _updatedAt with lazy initialization (??=) so dates are parsed once and then cached, consistent with other properties like _fields and _overview.
