feat!: remove NETNA_CONFIG and default ABIs to testnet

[WGB5445]

Summary

This PR removes the legacy Netna (chain id 208) deployment path, deletes the Netna ABI bundle, and aligns the SDK’s default ABI selection and unknown-chain_id fallback behavior with Aptos testnet (testnet.json). Public configuration exports drop NETNA_CONFIG in favor of TESTNET_CONFIG, with README and all read/write/WebSocket examples updated accordingly. It also adds a runnable examples/write/market_maker_bot.py reference implementation and updates ABI registry tests.

Changes

• Public API / config: Remove NETNA_CONFIG from exports and migrate NAMED_CONFIGS usage consistently to testnet.
• ABI registry: Remove CHAIN_ID_NETNA handling; default ABI data and warnings now fall back to testnet instead of Netna.
• ABI assets: Remove src/decibel/abi/json/netna.json.
• ABI generation tooling: Update get_abi_filename mapping to match the new configuration surface.
• Gas station defaults: Remove the Netna-specific gas station URL branch for chain_id == 208.
• Examples: Replace NETNA_CONFIG with TESTNET_CONFIG across examples; add market_maker_bot.py.
• Tests: Update tests/abi/test_registry.py for the new default/fallback behavior.

Motivation

Netna-specific ABIs and configuration increase maintenance burden and confuse onboarding relative to the current Aptos testnet deployment model. Centralizing on TESTNET_CONFIG reduces ambiguity and keeps defaults aligned with supported environments.

Verification

• Run the test suite (notably tests/abi/test_registry.py).
• Smoke-test a couple of read/write examples against testnet (use dry-run where applicable for trading flows).

Breaking changes

• NETNA_CONFIG is removed from decibel exports.
• Default ABI selection no longer uses Netna; consumers relying on Netna-specific ABIs must migrate to an explicit supported configuration.

Pull request overview

Removes the legacy Netna (chain id 208) configuration/ABI path and changes the SDK’s default ABI selection and unknown chain_id fallback to Aptos testnet, updating exports, docs, examples, and tests accordingly.

Changes:

• Removed NETNA_CONFIG from public exports and NAMED_CONFIGS; adjusted gas station defaults to drop Netna-specific URL handling.
• Updated ABI registry/generation logic to remove chain id 208 and default/fallback to testnet.json; deleted the Netna ABI bundle.
• Migrated all README/examples from NETNA_CONFIG to TESTNET_CONFIG and added a runnable market_maker_bot.py example.

• get_abi_filename() now falls back to f"{config.network.value}.json" for non-testnet/mainnet configs. Since both LOCAL_CONFIG and DOCKER_CONFIG use Network.CUSTOM, this will generate the same filename (custom.json) and can overwrite outputs when fetching multiple networks. Consider special-casing LOCAL_CONFIG/DOCKER_CONFIG (e.g., local.json / docker.json) or incorporating a stable discriminator (like the named config key or chain_id) into the filename.
