Add base account connector

[yashovardhan]

Adds base account connector for v11 on top of the changes done here for v10: #2340

Tested with the vue-app-new

Note

Medium Risk
New wallet connection path and provider selection logic (including AA bypass) affect authentication and transaction signing for EVM users; scope is limited to an optional connector and demo wiring.

Overview
Adds a Base Account EVM external connector (v11) using @base-org/account, mirroring the existing Coinbase connector pattern: init via createBaseAccountSDK, connect with eth_requestAccounts, and chain switch/add handling.

SDK surface: @web3auth/no-modal exposes baseAccountConnector and types; @web3auth/modal re-exports it from a new ./connectors entry (alongside coinbase). @base-org/account is an optional peer on modal and no-modal.

Wallet / AA behavior: Registers WALLET_CONNECTORS.BASE_ACCOUNT (base-account) with login param typing. Account-abstraction wrapping is skipped when the active connector is Base Account, since it is already a smart-account style provider.

Demo: vue-app-new can select base-account-connector, imports connectors from @web3auth/modal/connectors, fixes the connector loop off-by-one, and runs the connectors watcher with immediate: true. Vite pre-bundles @base-org/account and @coinbase/wallet-sdk.

Also bumps workspace packages to 11.2.0 and React overrides to 19.2.7, with lockfile updates for the new dependency tree.
