Add IPFS blockstore and browser signer
Introduce IPFSBlockstore that stores repo blocks via a local Kubo HTTP
RPC and remove the SQLite-backed blockstore. Add a SignerHub and
WebSocket signer endpoints (bearer and cookie) to support a browser-
based signer, BYOK registration via Ethereum wallets, and service-auth
JWT signing with caching. Add x402 pinning config/hooks, update CLI
flags, server config, handlers, and templates for account/signup/signin
and home pages.

* Switch to the new repo lib

* Fix nil pointer

* caching

* clean

* fix: empty array nil

* use make for array init

* bump indigo version

* fix TIDClock ptr

Instead of returning an error when encountering an empty or invalid CID,
log the error and continue processing the remaining blobs.

* feat: log level configuration

Add a new `--log-level` flag to configure the logging level for the
server. The flag accepts values: debug, info, warn, and error. The
default log level is set to info. The log level is passed to the server
and used to filter log messages based on the configured level.

* fix: log level arg

* feat: configurable session cookie key

* chore: fmt
