fix(fleet): support selector rules and disambiguate same-name ships

[yltx]

Summary

• add FleetRuleRequest and plan.fleet_rules support in task schemas/routes
• propagate fleet_rules through normal/event fight ops and preparation flow
• enhance fleet change algorithm with selector-aware matching, refill, and occupied-slot handling
• support search_name in choose-ship flow to disambiguate same-name ships (e.g. 大淀 variants)
• bump package version to 2.1.9.post5

Why

Frontend now sends slot-level fleet selector rules (candidates/search_name). Without backend support, same-name ships can be treated as already matched and fail to replace, causing repeated fleet setup failures.

Validation

• local static check on modified files passed
• branch pushed and ready for review

Pull request overview

This PR adds backend support for slot-level fleet selector rules (candidates/search_name/level range) and improves fleet-changing + ship-choosing logic to handle same-name ships and selector-driven matching, then propagates the new fleet_rules field through server schemas/routes into normal/event fight preparation. It also bumps the package version.

Changes:

• Add FleetRuleRequest + plan.fleet_rules to task request schemas and route overrides.
• Enhance fleet-change flow to be selector-aware (candidate reuse, one-to-one matching, refill/occupied-slot handling) and extend choose-ship flow with search_name + optional level filtering.
• Update ship-list OCR utilities to support optional name de-duplication disabling and row-level keys for correlating name ↔ level OCR results.

• read_ship_levels() now optionally appends row_key to each entry, but the debug log still unpacks found as (n, lv) pairs. When include_row_key=True (used by ChooseShipPage._click_ship_in_list for level filtering), this will raise ValueError: too many values to unpack and break ship selection. Update the debug formatting to index into the tuple (e.g., entry[0], entry[1]) or branch on tuple length.

    _log.debug(
        '[选船列表] 等级识别: {}',
        [(n, lv) for n, lv in found],
    )
