chore(web): deduplicate storage template examples

[Snowknight26]

Description

Deduplicate storage template examples and re-use the same date. The only difference post-refactor is that the browser's time zone will be used to display the example.

Continuation of #26424.

How Has This Been Tested?

• Viewed the Storage Template examples

Screenshots (if appropriate)

Checklist:

• I have no unrelated changes in the PR.
• I have confirmed that any new dependencies are strictly necessary.
• I have written tests for new code (if applicable)
• I have followed naming conventions/patterns in the surrounding code
• All code in src/services/ uses repositories implementations for database calls, filesystem operations, etc.
• All code in src/repositories/ is pretty basic/simple and does not have any immich specific logic (that belongs in src/services/)
