Cross-link E7.M1 doc to E7M3 five-quest roster; remove dead
_prototype_e7m1_quest_gate; add faction standing-band CI gate;
clarify server roster error strings; grid-contract loader test asserts.
Add two prototype factions, extend quest bundles with reputationGrants
and factionGateRules, freeze five-quest roster in validate_content.py,
and sync minimal server quest roster parity for green startup tests.
Rename freeze-first loader tests, add PrototypeE7M2QuestCatalogRulesTests
for cross-ref paths, align missing skill-def error with Python, and
document bundle schema path resolution in server README.
Register bundle JSON Schemas, parse bundle DTOs on QuestDefRow, and run
E7M2 prototype gates (presence, freeze table, cross-ref, mission_reward)
with skill catalog input from DI.
