feat(core/eckhart): cache THP app/host name along with MAC

What changed, and why it matters
This commit is a small feature update for the Trezor hardware wallet's Bluetooth pairing system. It adds a new 'app_name' field to the cached information stored alongside each paired device's MAC address and host name. The change is purely additive and does not appear to fix or introduce any security vulnerability. It updates protocol definitions, device menu display helpers, pairing logic, and generated code in multiple languages, plus related tests.
Recommended action
No security action required. Treat as normal feature commit. If reviewing for release readiness, verify that the new required protobuf field does not break backward compatibility with older host software that may not send app_name during pairing.
Security signals we found
01
No security-relevant keywords in commit title or message
02
No changelog entry, consistent with routine feature work
03
Additive schema change only; no validation, crypto, or authorization logic modified
04
No input parsing changes beyond existing trim_str length limit
05
No references to CVEs, advisories, or security reports
Evidence from the diff
The commit extends the THP (Trezor Host Protocol) paired-device cache schema by adding a required string field app_name to ThpPairedCacheEntry. It updates the protobuf definition, generated Python and Rust message classes, the firmware’s pairing cache helper, and the device-menu UI helper that looks up host names. The new field is trimmed to 32 bytes and stored with the existing mac_addr and host_name. Test expectations for serialized cache size are adjusted accordingly. No security fixes or vulnerability indicators are present in the diff.
