chore: back-merge prod into development

[DeepakSingh80]

Phase 1 T4 of the native SDK CI/CD runbook (docs/hlds/native-sdk-cicd/phase-1-runbook.md).

Why

development is behind prod. T8.3 renames development → dev and makes it the integration branch; if this lands after the rename, the divergence is frozen into the new branch contract. So it goes in first.

What merges in

development is an ancestor of prod — 0 commits ahead — so this is a clean fast-forward. No conflicts.

Ten commits, spanning releases 7.4.4 → 7.7.0:

26b8085 Release v7.7.0 (#199)
f1c0794 chore(release): 7.6.2 (#200)
dc1952f Merge pull request #198 from smallcase/release/v7.6.1
2477b33 chore(release): 7.6.1
81774d5 chore(android): bump Loans SDK to 5.3.1
eb2c5d5 Merge remote-tracking branch 'origin/prod' into development
4883b70 Release/v7.6.0 (#197)
2b429ca Merge pull request #194 from smallcase/release/v7.4.4
1fcbec2 chore(release): 7.4.4
f46bcfd chore(prod): bump up gw sdk Android native to 6.1.2

Net effect on the pins and version:

	development	after merge
package.json version	7.4.3	7.7.0
com.smallcase.gateway:sdk	6.1.1	6.1.2
com.smallcase.loans:sdk	sdk-sourav-native-dark-theme-cb54bf9:5.1.4-92-release	sdk:5.3.2
SCLoans	SCLoans-sourav-native-dark-theme-37c97d9 7.1.2-45-release	SCLoans 7.4.0

This supersedes #204 (T3)

#204 reverted the internal dark-theme remix pins by hand, using prod as the reference. prod already carries that exact revert — byte-identical in both files — so this merge does T3's job as a side effect. #204 should be closed unmerged once this lands; merging both is redundant, not harmful.

The runbook's T3/T4 sequencing warning ("expect conflicts in package.json and the podspec") does not apply: the conflict it anticipated only exists if T3 merges first.

Test plan

• Android: com.smallcase.loans:sdk:5.3.2 and com.smallcase.gateway:sdk:6.1.2 resolve from the public SCGateway Artifactory repo, not SCGateway-internal.
• iOS: pod install in smart_investing_react_native resolves SCLoans 7.4.0 / SCGateway 7.2.0.
• yarn install --frozen-lockfile succeeds against the merged yarn.lock.
• Dark-theme behaviour is re-verified against the released SDK, or confirmed as unshipped — the remix was an internal test build.
