feat(core): use "Initiate connection" bootloader label on T2T1, T3B1, T3T1
Replaces the outdated "INSTALL FIRMWARE" / "INSTALL FW" button label on
the bootloader intro screen with one that accurately describes what the
button does — initiating the USB/host connection.
T3W1 (Safe 7) already used "Initiate connection"; this aligns all other
Core devices with that wording. T3B1 (Safe 3) uses a shortened "Init
connection" to fit the 128×64 pixel display.
Closes #6824

What changed, and why it matters
This commit only changes the text label on a bootloader button from 'INSTALL FIRMWARE'/'INSTALL FW' to 'INITIATE CONNECTION'/'Init connection' on three Trezor hardware wallet models. It is a user-interface wording improvement with no security or functional code changes.
No security action needed; this is a cosmetic label change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies three Rust UI layout files for the Trezor bootloader intro screen. In each, the text string assigned to the host-connection button is updated: layout_bolt and layout_delizia use ‘INITIATE CONNECTION’ instead of ‘INSTALL FIRMWARE’; layout_caesar uses ‘Init connection’ instead of ‘INSTALL FW’. No logic, event handling, styling, or behavior is altered.
