fix: don't hide time codes in portrait or narrow window

[Samillion]

Instead of hiding the time codes, move them above play controls, centered.

Centered above play controls is the best fit, as these buttons do not have tooltips and places the essential elements centered so even in abnormal narrow videos or window, they're displayed.

Sorry for the random ping, looking for feedback on this PR before I merge, Only if it's not a bother.

Test script: portrait_videos_tc/modernz.lua

That's an awesome idea. I definitely approve.

You might see a clash/overlap of elements with larger font sizes (such as 18) or when milliseconds are enabled.

[Samillion]

True! I did not think of that. I'll apply a fix for that one in a different PR, thank you so much for pointing it out. Completely slipped my mind.

[jiangzhenjerry]

Thanks for pinging. So far so good on my end. time_font_size >=20 may make it look a little crowded for portrait videos but 18 and below works well. Love it.

[Samillion]

Awesome, thank you for confirming. I'll apply a PR fix for time state and font size after merging this one.
