[Feature] Allow default values for Time and Timezone when editing photo metadata via web interface

I have searched the existing feature requests, both open and closed, to make sure this is not a duplicate request.

The feature

When editing the date and time of a photo via the web interface, a form appears requiring the following mandatory fields:

• Date and Time
• Timezone

It would be beneficial if:

1. You could set only the date, with the time defaulting to a standard value (e.g., 12:00:00.000).
2. You could set only the date and time, with the timezone defaulting to the value specified in your .env file.

Regarding point 2, I have configured a default timezone in my .env file, as suggested in https://docs.immich.app/overview/quick-start/ and #17169, and I have noticed that there are many ongoing discussions regarding timezones, yet this specific issue does not seem to be addressed.
My workflow often involves adding images by simply pasting them into the web interface; because these images lack EXIF data, they are assigned the timestamp of when they were pasted. Unfortunately, when I attempt to modify the date and time, they are assigned a random timezone (rather than the one set in my .env file), meaning I must manually correct it every time. It would be excellent if this step could be avoided.

Furthermore, regarding point 1, it would be very helpful if I did not have to manually adjust the seconds and milliseconds that are automatically applied when pasting images, as these are unnecessary.

We should probably infer the default timezone from the server TZ variable.

I personally do not think configuring a default time is worth it for a relatively edge use case as we already have bug/issues around this picker and this would only add to that.

Are you suggesting we implement 2. while omitting 1.?

Should we formalize this via a new issue, or document 2. elsewhere?

That is my suggestion. There is no need to open an additional feature request, it is covered here.
