feat: workspace component create should reject unknown parameter names

[TomProkop]

Problem

txc workspace component create silently ignores unknown parameter names. If an AI agent or user passes --param FormatName=Email (a hallucinated parameter), the command succeeds but the parameter has no effect — the attribute is created without the email format.

Expected behavior

The CLI should:

1. Validate all --param key=value entries against the template's actual parameter list
2. Reject unknown parameter names with a clear error: Unknown parameter 'FormatName' for template 'pp-entity-attribute'. Did you mean 'TextFormat'?
3. Optionally suggest the closest matching parameter name (fuzzy match)

Impact

Silent parameter ignoring is the most dangerous form of hallucination impact — the command appears to succeed but produces wrong output. The developer only discovers the problem at import time or during roundtrip diff.
