[francois-guerin-ledger]

📝 Description

Introduce config_generic_a4 a cross-family LiveConfig key driving A4 indexer integration.

• Zod-validated schema with per-chain enabled/registerOnly switches and environment (stg/ppr/prd).
• resolveA4ChainConfig(currencyId) returning { read, register, environment } with log-once fallback
• Default config: all 60 A4-supported networks at { enabled: false, registerOnly: true }
• Registered in sharedConfig.ts

🔗 Context

Pull request overview

This PR adds a new LiveConfig entry (config_generic_a4) to @ledgerhq/live-common and wires it into the shared LiveConfig schema, along with a resolver helper and Jest coverage to interpret the config at runtime.

Changes:

• Register a new LiveConfig key config_generic_a4 and include it in liveConfig aggregation.
• Add a4 LiveConfig schema + Zod parsing and resolveA4ChainConfig() resolution logic.
• Add unit tests for resolver behavior and the config schema defaults.

• The parameter name network is ambiguous given that this resolver is keyed by the A4 network id strings (e.g. "avalanche_c_chain"). Renaming it to networkId would better communicate what callers must pass.

export function resolveA4ChainConfig(network: string): A4ChainResolution {

libs/ledger-live-common/src/bridge/generic-coin-framework/a4/config.ts:146

• The catch block can only be reached when LiveConfig.getValueByKey throws because the global LiveConfig schema was never set (it throws "Config not set" when config is empty). The log message currently implies only config_generic_a4 is missing, which is misleading when debugging.

  } catch {
    if (warnedConfigMissing) return A4_OFF;
    warnedConfigMissing = true;
    log("a4", "config_generic_a4 not set in LiveConfig - A4 disabled");

libs/ledger-live-common/src/config/sharedConfig.ts:33

• Repo review guidance flags libs/ledger-live-common/ as maintenance-only (see .agents/agents/code-reviewer.md:44). This adds a new feature module under src/bridge/generic-coin-framework/a4/. If this is expected, it would help to confirm (or consider placing this in a more appropriate package) to avoid further feature growth in live-common.
