Original task statement excerpt

[BUG] Kinesis: IncreaseStreamRetentionPeriod with same value should be a no-op (not an error)
## Service

Kinesis

## AWS API Action

`IncreaseStreamRetentionPeriod` — `POST /` with `Action=IncreaseStreamRetentionPeriod`

## Related issue

This is a follow-up to #291 (which added the `IncreaseStreamRetentionPeriod` implementation). The API now exists but its error handling differs from real AWS in an edge case that breaks Terraform.

## Expected behavior (real AWS)

On real AWS, calling `IncreaseStreamRetentionPeriod` with the **same value** as the current retention period is a **no-op** — it returns success without error.

```bash
# Stream already has 24h retention
aws kinesis increase-stream-retention-period \
  --stream-name my-stream \
  --retention-period-hours 24
# ✅ Returns success (no-op)
```

This is important because Terraform calls `IncreaseStreamRetentionPeriod` on every apply when the `retention_period` attribute is set, even if the value hasn't changed.

## Actual behavior (Floci 1.5.2)

Floci returns `InvalidArgumentException` when the requested retention period equals the current retention period:

```
InvalidArgumentException: Requested retention period (24 hours) must be 
greater than current retention period (24 hours)
```

This is technically correct per the API name ("increase"), but it differs from real AWS behavior and causes Terraform to **taint the Kinesis stream resource**. Tainted streams cause cascading failures — dependent resources like Lambda Event Source Mappings fail to create.

### Reproduction

```bash
# Start Floci
docker run -d -p 4566:4566 hectorvent/floci:latest

# Create a Kinesis stream (default retention: 24h)
aws --endpoint-url http://localhost:4566 kinesis create-stream \
  --stream-name test-stream \
  --shard-count 1

# Set retention to 24h (same as default) — this should be a no-op
aws --endpoint-url http://localhost:4566 kinesis increase-stream-retention-period \
  --stream-name test-stream \
  --retention-period-hours 24
# ❌ InvalidArgumentException: Requested retention period (24 hours) must be 
#    greater than current retention period (24 hours)
```
