# Fix Typos in `LightClient.t.sol` and `api.rs`

## Description
This pull request fixes minor typos in the following files:

1. **`contracts/test/LightClient.t.sol`**:
   - Corrected `initiazing` to `initializing` in a comment.

2. **`sequencer/src/api.rs`**:
   - Fixed `atleast` to `at least` in a log message.

## Changes
- These changes improve code readability and maintain high-quality
documentation and logs.
- **No functional changes**: The updates are purely related to comments
and log messages.

### Context
Maintaining proper spelling and clarity in comments and logs ensures
better code quality and easier maintenance for all contributors.
