docs: replace legacy CDP wallet provider references across docs

The docs, issue template, and Python contributing guide still referenced
wallet providers that were removed or renamed during the CDP Wallet API v2
migration (`CdpWalletProvider`, `SmartWalletProvider`/`CDPSmartWalletProvider`,
`EthAccountWalletProvider`, `CdpV2SolanaWalletProvider`,
`PrivyEvmDelegatedWalletProvider`, `cdpWalletActionProvider`). New users who
copied snippets from these docs hit import errors and confusing config shapes.

This sweep:

- Updates `typescript/agentkit/README.md` and `python/coinbase-agentkit/README.md`
  to use `CdpEvmWalletProvider` / `CdpSmartWalletProvider` / `CdpSolanaWalletProvider`
  with the current `apiKeySecret` + `walletSecret` config surface, and drops
  the stale `SmartWalletProvider` and `CDPSmartWalletProvider` sections.
- Adds the required `cdpWalletSecret` / `CDP_WALLET_SECRET` to the default
  `AgentKit.from(...)` examples in the TS core README and the Langchain, MCP,
  and Vercel AI SDK framework-extension READMEs.
- Switches Python framework-extension setup instructions from the removed
  `CDP_API_KEY_PRIVATE` env var to `CDP_API_KEY_SECRET` + `CDP_WALLET_SECRET`.
- Fixes the Python contributing guide's action-provider walkthrough so it
  uses the canonical `Erc721ActionProvider` / `EvmWalletProvider` shape with
  a `send_transaction` + `wait_for_transaction_receipt` flow instead of the
  removed `CdpWalletProvider.mint` helper.
- Updates the bug-report issue template to reproduce with
  `CdpEvmWalletProvider` + `walletActionProvider`, and corrects the TypeScript
  snippet to use `//` comments instead of `#`.
- Fixes the Compound action provider README test example to construct
  `CdpEvmWalletProvider(CdpEvmWalletProviderConfig())`.
- Fixes the Across action provider README to refer to `CdpEvmWalletProvider`
  and the x402 README to import from `@coinbase/agentkit` (was
  `@coinbase/cdp-agentkit`).
- Updates the generator-script README example to use `CdpEvmWalletProvider`.
