refactor(networks): introduce branded network symbol

[peter-sanderson]

Description

This PR introduces the layer-independent @trezor/network-module package with an open branded NetworkSymbol, replaces the generic Suite Common module registry with independent non-generic modules, and keeps each network family’s exhaustive literal union isolated behind explicit boundary conversion. Connect’s asCoinSymbol helper is now supplied by merged PR #30611 on develop.

• Registry shape: 7 keyed fields → readonly SuiteCommonNetworkModule[]
• Branch history: 10 commits → 1 commit
• Focused type-check: 12 packages passed
