## Issue
4796 - i18n: Allow support for string overloading (multiple contexts)
## Approach
- Minimal code and process change.
- Handle on a case-by-case basis when reported by translators.
- Split the affected key in the string json by appending the context.
- Translators need to be aware of the new format and not translate context itself. Code is added to detect bad translations and will revert to English.
Sample in json:
"About --[About section in Help Page]--": "About",
"About --[tab title in Channel Page]--": "About",
Sample in client code:
title={__('About --[About section in Help Page]--')}
- "--[ ]--" was chosen as it's unique enough (unlikely for real strings to use it) and hopefully not that distracting in the client code.
- In the key itself, spaces are allowed after the string (i.e. before '--[') for neatness. It will be trimmed by the system.
## First example
"About" is used in 3 places:
- Channel Page
- Help Page
- Footer (in Odysee branch)
For Russian, the word "About" is "O" and is usually not used standalone, but requires something behind it. A translator said so, and seems to be the case in other sites as well.
"O xxx"
"O yyy"
## Other languages
For other languages that are not impacted, they can just clone the same translation for each of the split keys, just like in English.
## Possible enhancement in Transifex
I see that Transifex's API includes a `context` entry. It might be possible to move the context-metadata there during the upload, so translators will never see the "--[]--" messiness (it will be shown as "Context: xxx" in the Transifex GUI).
I'm not sure how to test the Transifex side, so I did not investigate further.
Most of the items in the footer don't need to be translated, but it was troublesome trying to make `sections[]` re-resolve the label on a language change, if we want to selectively translate certain labels only.
So, just translate everything for now. Translators can simply clone the English string if it doesn't need a translation.
## Issue
4831: Videos start muted on Desktop (fresh install) and web (sometimes resets)
This covers the Desktop fresh install and Web fresh session (incognito) part. It doesn't cover the "sometimes reset" part as I don't know how to reproduce that.
## Change
`sessionStorage` is always empty when that piece of code is called, even for non-fresh Desktop and even in Brave. We now fallback to `1` when `volume` is `null`. Still not sure the purpose of that code, but leaving it there just in case something relies on it.
## Tests
[/] Desktop fresh-install is not muted.
[/] Desktop return session restores previous volume level.
[/] Web* fresh session (cleared data) is not muted.
[/] Web return session restores previous volume level.
*Web = Chrome, Firefox and Brave.
