feat(orders): complete IB algo builder coverage (9 new strategies) (#522)

* refactor(orders): extract algo_builders inline tests to sibling file

Per CLAUDE.md rules 13/14: tests in their own file, modernize touched
modules. Sibling _tests.rs wired via #[path] attribute, contents
unchanged. Prepares the module for upcoming algo builder additions
without mixing test relocation into the feature diffs.

* feat(orders): add Adaptive, ClosePrice, DarkIce algo builders

Priority 1 of the remaining IB algo strategies:
- AdaptiveBuilder ("Adaptive") + AdaptivePriority enum
- ClosePriceBuilder ("ClosePx"), reuses RiskAversion
- DarkIceBuilder ("DarkIce")

Each ships with a fluent builder, helper function in algo_helpers,
TryFrom<Builder> for AlgoParams, struct + helper doc-examples, and
round-trip + minimal-form tests. Mirrors the pattern established by
the existing 4 builders.

* feat(orders): add AccumulateDistribute, BalanceImpactRisk, MinimiseImpact algo builders

Priority 2 of the remaining IB algo strategies:
- AccumulateDistributeBuilder ("AD") - 9 fields covering component
  sizing, time/size randomization, and active-time windows
- BalanceImpactRiskBuilder ("BalanceImpactRisk") - reuses
  RiskAversion + validate_pct_vol
- MinimiseImpactBuilder ("MinImpact") - single max_pct_vol field

Each ships with helper, TryFrom, struct + helper doc-examples, and
round-trip + minimal + boundary tests for percentage validation.

* feat(orders): add PctVolPx, PctVolSz, PctVolTm algo builders

Priority 3 - the three specialized PctVol variants:
- PctVolPriceBuilder ("PctVolPx") - rate varies with price
- PctVolSizeBuilder ("PctVolSz") - rate varies with remaining size
- PctVolTimeBuilder ("PctVolTm") - rate varies linearly over time

Validation deviates from the original plan: only participation-rate
fields (pct_vol, start_pct_vol, end_pct_vol) are checked against
the 10-50% range. delta_pct_vol can legitimately be negative, and
min_pct_vol_4_px / max_pct_vol_4_px h... (continued)
