feat(web): add millisecond options to storage template settings

[sevtdy]

Proposing to add an option for SSS (milliseconds) to the storage template.

Currently, my storage template setting looks like this:
{{y}}/{{y}}-{{MM}}/{{y}}{{MM}}{{dd}}_{{HH}}{{mm}}{{ss}}
UPLOAD_LOCATION/admin/2022/2022-02/20220203_045605.jpg

Although immich append +1, +2, etc. when the filename is duplicated, I would prefer to avoid this.
I believe that adding an SSS (millisecond) option to the template would make more sense and be more suitable for most situations.

take my as example, ideally would be like this:
{{y}}/{{y}}-{{MM}}/{{y}}{{MM}}{{dd}}_{{HH}}{{mm}}{{ss}}_{{SSS}}
UPLOAD_LOCATION/admin/2022/2022-02/20220203_045605_055.jpg
UPLOAD_LOCATION/admin/2022/2022-02/20220203_045605_171.jpg

Nice. Do you want to add a preset with it?

@jrasm91 thanks for the prompt review.

I think it's okay to keep the preset unchanged. Time format preferences can vary greatly among different users. We can manually setup this.

Additionally, I've added a new commit to fix the test case. Kindly review it again.
