* feat: add refresh metrics action to Saved Keywords page
Adds an Actions dropdown to the Saved Keywords header with an
"Update keyword stats" option. Fetches fresh volume, CPC, competition,
difficulty, and intent from DataForSEO for all saved keywords in the
project, grouped by location/language. Mirrors the existing refresh
pattern from Rank Tracking.
Closes#49
* fix(keywords): preserve full metric shape on saved-keyword refresh
Align refreshSavedKeywordMetrics with the research/save persistence shape
so a refresh never degrades stored data:
- Persist real monthly_searches trend instead of writing "[]"
- Derive Google Ads competition from competition_index/100 instead of null
- Normalize intent via normalizeIntent (Labs) / "unknown" (Ads) to match
mapKeywordDataItems / mapAdsKeywordItems
Also extract the per-batch fetch+map into fetchBatchMetrics to resolve the
oxlint max-depth violation, and apply prettier formatting so ci:check passes.
