feat(api): surface node mode identity on the overview page

[arkadianet]

What

The dashboard never rendered /api/v1/identity despite the endpoint being registered in the web client and the ApiIdentity.mode doc comment stating it was designed for the dashboard hero strip. The overview's top row now shows the mode label ("archive · utxo", "digest-verifier", "pruned · utxo · keep N", …) with compact pills for mining / extra-index / verify-tx and bootstrap provenance (shown only when a jump actually ran). Fetched once on mount (static config), hidden on fetch failure — the page never breaks.

Plus one real bug

build_api_identity_from_inputs hardcoded mining: false — a live mining node reported mining:false on /api/v1/identity (same class as the /info isMining stub fixed in #7). IdentityInputs now carries mining_enabled from config; all constructors swept; unit test pins the flow both ways.

Verification

fmt/check/clippy(CI-exact) clean; cargo test -p ergo-node --lib 346 green; cargo test -p ergo-api green. UI matches the existing cockpit visual language (existing .pill components, token-based CSS, no new design primitives); assets are compile-time embedded so this rides the next binary deploy.

📝 Walkthrough

Walkthrough

The PR adds mining enablement tracking to the node identity model by introducing a mining_enabled field to IdentityInputs, sourced from config, and projecting it through the /api/v1/identity endpoint. The web overview UI now displays a cached identity strip showing node mode and feature flags (mining, extra index, verify transactions) with conditional bootstrap provenance chips. Layout styles are updated to center and space the new identity strip appropriately.

Changes

Node identity mining enablement and overview UI display

Layer / File(s)	Summary
Mining enablement field in IdentityInputs ergo-node/src/node/identity.rs	IdentityInputs gains a mining_enabled boolean field initialized from config.mining_config.enabled, and build_api_identity_from_inputs now populates ApiIdentity.mining from that field instead of the previous hardcoded false value.
Test coverage for mining flag projection ergo-node/src/node/tests.rs, ergo-node/tests/identity_live_refresh.rs	Test fixtures (make_state_with_backend, inputs_for, archive_inputs) now explicitly set mining_enabled: false, and a new test build_api_identity_mining_flag_tracks_mining_enabled verifies the mining field is correctly projected for both true and false values.
Node identity strip in overview UI ergo-api/web/js/overview.js	The overview page now includes a cached node identity strip displayed at mount time. The state.identity field stores identity data; fetchIdentity() calls the API once per session and caches the result; renderIdentity() populates the UI with node mode and feature flag chips (mining, extra_index_enabled, verify_transactions) plus conditional bootstrap provenance chips.
Overview cockpit layout styling ergo-api/web/dashboard.css	CSS for the Overview cockpit section (.ov-top, .ov-ident, .ov-ident__chips) is updated to center-align items, distribute with space-between, add explicit gaps, support flex wrapping, and prevent content overflow with min-width: 0.

A node's identity now shines so bright,
Mining flags flutter in the dashboard light! 🐰✨
Feature chips dance in their flexbox way,
While tests ensure they behave today.
