feat(protobufs): sync to firmware-current and consume workspace package (#1097)

* feat(protobufs): sync to firmware-current and consume workspace package

Sync the vendored .proto sources to firmware-current (v2.7.25+48), regenerate the v2 TS bindings, and consume the workspace @meshtastic/protobufs (workspace:*) in place of the stale JSR 2.7.20 — finishing the monorepo migration (core was already workspace:*).

Includes the one required breaking-change fix: admin nodedb_reset changed int32 to bool, so resetNodes() now sends value: true.

* build(protobufs): vendor generated bindings for workspace consumers

The package is consumed via workspace:* — its exports point at the TS source, which imports ./dist/meshtastic/*_pb.ts — so the generated output must exist at build time. CI builds web/core with no codegen step and the runners have no buf CLI, so the bindings are vendored here (kept gitignored; lint/format skip them). Regenerate with: pnpm --filter @meshtastic/protobufs gen

* fix(protobufs): clean script removes the actual generated output dir

buf writes bindings to packages/ts/dist, but clean was removing a non-existent root dist — so it never cleaned stale output. Addresses Copilot review feedback.

* refactor: move web app packages/web -> apps/web

Aligns the web app with the apps/web layout (matching the Vercel web-test Root Directory and the SDK-migration direction). Pure directory move plus root config: pnpm-workspace (adds apps/*), vitest projects, root tsconfig reference, and the pr/release-web/nightly workflows. vercel.json moved with the app. Build + 36 validation tests green.

* feat: config fields, module pages, key verification, telemetry capture

Incorporates the firmware-current feature work onto the protobuf foundation: new config fields (Display message bubbles; LoRa fem_lna_mode + serial_hal_only; Telemetry air_quality_screen_enabled); 4 new ModuleConfig pages (TrafficManagement, StatusMessage, TAK, RemoteHardware); the manual Key Verification flow (sendKeyVerification + ClientNotificationDialog stages + Verify Key button); live telemetry capture (nodeDB addDeviceMetrics) and admin hardening (toggleMutedNode, graceful PortNum default); plus the sdk-preview ConfigEditor demo and store/config tests. Build + lint + format + 131 tests green.

* chore: drop #1062 (unsaved-change-detection) to match upstream revert

#1062 was merged to main by accident (per @danditomaso) and is being reverted. Reverse-applied its diff here via 3-way so #1097 stays consistent with where main is headed, while keeping the feature changes layered on the same files (deviceStore/changeRegistry). Build + 131 tests + lint + format green.

* fix(nodes): clean up SNR display in node table and map popup

SNR is a ratio measured in dB, not dBm (which is absolute power); the
node table and map popup both mislabeled it and crammed three values
together: '0dBm/50%/50raw'. The trailing '%/raw' pair was the same
heuristic ((snr+10)*5) shown twice — once clamped, once not.

Render SNR in dB rounded to one decimal, color-coded by a 0-100%
signal-quality heuristic (green/yellow/red), with the quality percentage
as a muted secondary. Drop the redundant raw value. Adds unit.db; this
matches the existing SNRTooltip, which already renders dB.
