Simplifying messages / translations + small changes

[tadeubas]

What is this PR for?

• Simplified the below translations to just "Failed to load" :

"Failed to load PSBT",
"Failed to load address",
"Failed to load key",
"Failed to load message",
"Failed to load mnemonic",
"Failed to load output descriptor",
"Failed to load passphrase",

• Removed translations for extreme rare error messages (some in firmware.py):

"Maximum length exceeded (%s)",
"invalid public key",
"Invalid bootloader" ,
"Firmware exceeds max size",

• Reuse of function status_text on firmware.py
• Added try / except block around function that could raise an exception without informing the user in firmware.py
• Fixed very long key / passphrase not showing properly at the proceed screen on m5stickv
• Fixed key / passphrase not checking for too long input using keypad
• Usage of ValueError instead of flash_error when loading too long input for key / passphrase
• Usage of flash_error instead of flash_message for error messages on bkp encrypted mnemonic
• New poetry poe task alias for wonder-mv: simulator-mv

What is the purpose of this pull request?

I've read all changes here and have done random testing of these in simulator and on amigo. All seems ok to me.

Just a thought for a future commit (or future pr as it might be out-of-scope for this pr).

• multiple display.flash_text() calls in firmware.py are for errors rather than informative text, so perhaps display might appreciate a method like "display.flash_error()" as exists in pages.init so that it's obvious that firmware upgrade failed (before message disappears).

I agree, we should use the error color when an error appear in firmware.py. And sure, this can be done in another PR
