* fix(bedrock): strip bedrock/ prefix and URL-encode ARNs in get_bedrock_model_id for invoke path

The invoke path (used by /v1/messages → Anthropic SDK / Claude Code) called
get_bedrock_model_id() which, when falling back to the raw model string, did
not strip the 'bedrock/' routing prefix and did not URL-encode ARNs.

For a model like:
  bedrock/arn:aws:bedrock:us-east-1:<ACCOUNT>:inference-profile/global.anthropic...

the URL built was:
  /model/bedrock/arn:aws:bedrock:…/invoke-with-response-stream  

Bedrock returned a JSON error body.  LiteLLM's AWSEventStreamDecoder passed
those bytes into botocore's EventStreamBuffer which expects binary event-stream
framing.  Checksum validation failed on the JSON prelude (0x223a7b22 == ':{"')
producing a misleading botocore.eventstream.ChecksumMismatch instead of the
actual Bedrock error.

Fix: strip 'bedrock/' (and 'invoke/') routing prefix from model string, then
URL-encode if the result is an ARN — matching what the converse path already
does in converse_handler.py.

Fixes: LIT-3274

* fix(bedrock): use strip_bedrock_routing_prefix to handle compound prefixes

Address greptile review: the original fix used a loop with break, so
bedrock/invoke/arn:... only stripped bedrock/ leaving invoke/arn:...
which is not an ARN → fell through to .replace('invoke/','',1) →
bare unencoded ARN → same malformed-URL bug.

strip_bedrock_routing_prefix() iterates without break, correctly
stripping bedrock/ then invoke/ in sequence. Also adds test case
for the compound-prefix scenario.

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/test_litellm

This folder can only run mock tests.
