Fix GAAP misspellings in NLP reference files

[migueljette]

• Corrects 10 tokens across 4 transcripts where gap/Gap/Non-Gap were transcribed instead of GAAP/Non-GAAP in financial reporting contexts
• Also fixes the accompanying case tag (UC/LC → CA, LC → MC) to be consistent with correctly-spelled GAAP tokens elsewhere in the dataset
• Changes applied to both nlp_references and force_aligned_nlp_references

Test plan

• Verify no remaining gap/Gap/Non-Gap tokens in these 4 files that should be GAAP
• Spot-check surrounding context to confirm no unintended changes
